Here's one for you guys, especially those that are marriend and/or are in long term relationships. I'm 25 years old, and I've been with my girlfriend for over 7 years now (2nd last year of high school). She is/was my first everything (girlfriend, sexual partner, etc.). Yeah, I was a late bloomer. Anyways, we've talked a lot in the past about getting married and having a family. It's always been a matter of if, not when, we would get married. However, lately, I've been having a lot of doubts about my relationship. I guess, being that she's been my only girlfriend, I always wonder about what else is out there. Is the grass really greener on the other side? She always asks me, "why do you love me and want to be with me?". It seems like I never know the answer. My response is always, "because, that's the way I feel and I can't explain it". I feel so terrible that I can't tell her. Yesterday, I was talking to a friend of mine - who is about to propose to his girlfriend of 1/2 year - who was given some great advice on relationships. The other person said to him, "do you get excited every time you are going to see your SO?" (ie. going out for lunch when working at different places). My friend said he does as does his girl. As for me, I can't say that I do when I am going to see my girl. It was there when we were first together, but I guess I got into a routine. So, for those of you that are married or been with your SO for a long time, do you still get excited? I don't know if I feel this way cause my life is too routine. This issue has been tearing me apart for days now. I know my girl loves seeing me, and she always tells me that she's scared of losing me. I feel so bad. She doesn't deserve this. She doesn't know any of this though. One of my friends asked me if she was "the one", and I couldn't answer her. I just didn't/don't know. I guess I'm just trying to figure out if she is the one. How did you guys know that your SO is the one? Any insight would be appreciated.
