My last relationship was a long distance relationship that I was in for 2 and a half years. I think back on why it ended and there were a couple things that were building up that didn't make me happy, but I think the biggest thing was that I realized that I wasn't in love with him, I just simply loved him. I never had a boyfriend before him, so it wasn't until other things started happening in our relationship that I realized this. There was the fact that we seemed to be growing on different paths, and I felt like I was trying to work towards something while he wasn't. I guess in a way I felt like a mother- checking up on him.. which was fine because you always want to look after your SO, but it became a bit taxing on me that I guess I didn't know if I could trust I could rely on him to do something without having to remind him. He was a really great guy overall though. Caring and honest and smart and all that, and he knew how to handle my moodswings and was supportive, but I think about it and I don't think he was right for me in the end is all due to the passion-factor. I ended it but it took a good 3 weeks of reflecting and crying and all that to make sure I was making the right decision.
I'm in a relationship now and have been for a year and I'm very happy, and he has found someone and is happy and we are on good terms so it all worked out in the end.
