@Kyleah,
Sorry I was using my tablet and the spell check changed some words so I can see it can be confusing. I broke up with my 8 year relationship - we were kind of dating at that point more out of habit. I went solo - meaning no boyfriends no one. Just out having fun and dating not seriously.
Went on vacation met this guy liked him and so forth, he was persistent and we had a long distance relationship. Traveled across country a few times between the two of us. He decided he would make the big move and a year later we got married.
Crazy huh, dated someone for years and years and then end up marrying someone after knowing them a year. We have been married now 18 years end of this month with 2 girls.
When you least expect it - it can happen.
I think you need to let go until you are both at the very least free of who you are attached to. My story was to let you know, don't worry about it. After you are free and you go solo, you never know who and when you will meet someone. Someone better than the two (my opinion) you are involved with now. Think of it this way - a really good guy is not going to want to be involved with you while you are married/involved with someone else.
Reminds me of another story (i got a boat load) --- during that prior 8 year relationship, I went away for the weekend with some girlfriends of mine. While we were out having some fun, we bumped into some guys one of my friends knew. One of them was saying over and over I never meet nice girls like you. He seemed very interested in me. I was honest and told him I was committed to some one else. He kept after me. So I finally said, You know you say you want a nice girl. So would you want to go out with me knowing I was seeing someone else? He said yes. I then explained well I wouldn't be the nice girl you were seeking then. He didn't catch on - so I realized in any case he wouldn't be for me.
