Hi friends,

I just broke up with my live-in boyfriend of 4 years. I basically told him that I felt like we were on different paths and that I felt different. I told him that I didn't know who I was anymore, that I knew I was his partner and I knew I was my brother's sister, etc. I told him that it wasn't right for me to stay with him if I didn't know these things and that I needed time to figure it out. He was calm and asked me a few reasonable questions (eg: how long have you been thinking about this?). After a while, he simply said "alright" and said that he never wanted to hold me back... So, I packed a few things and went to stay with a friend. He offered to help carry my bags to my friend's car.

But, I feel a lot of regret right now. This is the longest and most serious relationship that I have been in, ever. On the flip side, I really think we were headed in different directions, with different priorities (there's a past of drug use, and I'm trying to get/stay clean...). I'm finding it really hard to focus and concentrate because I do still love him, he's my best friend, and he has given me so much support in my life (I have a bad history -- loss mother to breast cancer, abusive dad, oldest of many kiddos). I told him during "the talk" that I will be forever grateful for his support and that he's helped make me a better person. He feels like he wasted 4 years, though.

I'm safe and staying with a friend. However, I'm fighting the urge so bad to go back. But at the same time, I'm still surprised by his initial response and I feel really confused right now. Did I make the right decision? My gut is telling me that I've made a mistake and that I'll regret it. What are my next steps?
