She's not married
yet. But at this point, I'd say she's as
good as married. And once a girl is married, that makes her none of your business. Now if you and her had ever had anything beyond friendship in the past, and she was
just engaged like she is now, and not married, I'd say go for it because you never know. Odds certainly wouldn't be in your favor, but you never know. But there's things you need to consider before you pursue
anything.
1. How long has it been since you talked to this woman last? Is there a reason why you haven't, or for that matter
she hasn't, made any contact with you before now?
2. Do you really just want to wish her well and/or express sorrow over her disability? (I would avoid doing the second part of that no matter what, BTW. I can't think of a non-awkward way to do it or why it would even be necessary to bring it up.) Or are you still in love with her and the thought of seeing your dream finally, truly die seems like too much to bear even though all it ever really was was a beautiful dream? You need to seriously ask yourself, were you content just being her friend when she actually was a part of your life? If you weren't, why would things be any different
now? Don't kid yourself into thinking you want her friendship when you really just
want her.
3. So you've found the love of your life, and you're engaged to that person, and you're busy planning the wedding and dreaming about spending the rest of your life with that person. Do you want former significant others and platonic friends with unrequited attraction to you
ever trying to reenter your life, let alone during
this period of time? Certainly there might be exceptions on a case-by-case basis, but I'm guessing the answer to that is "no" the vast majority of the time. If she wanted you to be a part of her life, wouldn't
she have initiated some contact by now? (I'm not saying that's necessarily the case, but it's something you need consider.)
I'm speaking from experience here. I had a friend who'd I'd known since third grade, and she was pretty cool (for a girl), and as we got older she got REALLY cool for a girl. We were really good friends, and we'd drift apart, but we always wound up back in each other's lives somehow. Long story short, in my mid-twenties, after years and years of friendship and a not-so-secret crush, I fell in love with her and wanted to marry her. I thought for sure she was the "the one", (and if she had loved me in return, no doubt she
would have been.) She never led me on, and she was honest with me from the very beginning the extent that she was willing to be a part of my life, and anything beyond friendship just wasn't in the cards. So we had kind of a brother and sister thing going on there for a while. I really did try to be her friend, and it was hard (especially because she was perpetually single), but in hanging out with her I fell more and more in love with her until one day I just couldn't handle it anymore and did, well,
this, basically. Aaand, she shot me down, aaaand she
still wanted to be friends! Really! She wanted things to stay the way they'd always been, and part of me wanted that too because I knew that was all of her I'd ever have. I told her honestly that I was willing to try that, that I was willing to have her in my life however I could get her, but that she needed to know that I was always going to want more. We attempted that ill-fated arrangement, and it was emotionally draining and damaging for both of us. We weren't compatible anymore because we wanted different things from one another that we weren't able to give. And eventually we just quit talking. We weren't enemies and we didn't hate each other; in fact, we really cared about each other. And because the situation we were in wasn't fair to either of us, we couldn't be around each other anymore. That was two or three years ago, and I missed her every day, both because I really missed her friendship and because I was still horribly in love with her.
I found out she got married this summer, and I was inconsolable for about a month. I would cry like a baby for hours at a time, wake up in the middle of the night and cry some more, and sometimes completely out of the blue I'd just break down in the middle of something and cry. And for a while, I debated whether or not I should "do the right thing" and congratulate her, but after some long deliberation, I decided against it. For one thing, my feelings for her still hadn't been properly dealt with, and she knew me too well for me to even entertain the notion of hiding those feelings. For another, I wanted her to be happy, and even though it hurt, me trying to be a part of her life again was not conducive to her happiness. If I
really loved her as much as I said I did, that meant I had to put her happiness ahead of mine. And her happiness was contingent upon not having to endure a relationship with someone who wanted something from her she couldn't give. And you know what?
My happiness was contingent upon the same thing! So me attempting to be a part of her life again wasn't good for either of us if we were going to be happy. Sure, I'm still hopeful that some day we really can be friends again like we were, but I needed to figure out how to be okay even if that never happens. That's the conclusion I came to anyway. Your mileage may vary.
