Hmmm, I'm going to risk getting called “weird and old again”, but I've been around a little longer than you. In fact I'm probably old enough to be your mother, but enough of that. I want to start off by saying that I'm not trying to stir crap, or instigate anything. I'm too tired for that nonsense. A question was posted and I'm just putting in my opinion. Nothing that I say is meant to insult anyone or hurt anyone's feelings.
Here is how this he said/she said crap usually works out…
1. Mutual attraction
2. Possibly jump into a physical relationship too soon and damn it's good
3. Figure out you have NOTHING in common
4. Fight/bicker/argue a lot
5. Get married anyway thinking this is going to solve some problems
6. Figure out it didn't solve problems but created a whole new set of them
7. Start wondering “Was I on crack at the wedding? Not only do I not have anything in common with this person, I'm not sure I even like them.”
8. Divorce proceedings begin and you get to fight over 1/2 of each others stuff. Hopefully, no kids are involved.
9. Both stay single for a while and try to straighten out the financial mess that divorce inevitably creates.
10. Each finds someone that has similar interests, financial habits, morals, goals, standards and dreams for the future.
11. They each live happily ever after without each other.
Now I'm not saying this is going to happen to the OP but I've seen this play out with friends and family, myself included, too many times. Ask yourself “What do we have in common? Why do I love her? Her looks? Her smile? Am I here because I feel like I'm expected to be?” You have to do what is best for you, and in the long run, for her. I'm not saying dump her or anything like that. But I do think it's time the two of you sat down and had a serious conversation about the future and what you both want and need to live happy, healthy, productive lives without any drama. Life is too damn short to be unhappy! Good Luck to you both and I really mean that.
