New Beau vs Old Flame

Samantha
I have been with my boyfriend for 2 years now and we just bought a house last year. I thought he was the one until an old friend of mine from high school and I met up at my new job. We see each other every day and it feels like nothing has changed. At the same time my boyfriend has been controlling and we have been having a lot of problems. I want to leave my boyfriend for my old flame but I can't just let my responsibilities go. Help?!? PS my old flame is married- for 3 years... 😥
