Confused

I just had the best sex ever and Jesus. It was with my boyfriend of 7 months and I'm very much in love with him, he's everything and the sex is just a plus, he knows all my spots and just what I like. I love it I love it, but when me and my boyfriend took a break I was having sex with this other guy (I know not a good idea) and I just really started to like him a lot I don't know why, and me and him don't talk anymore cause he's an asshole and I have a lot of pride. Last time I went to his house he was on his phone texting other females and shit, the 5 hours I was there I barely got 5 minutes of conversation And I don't know what's making me want him so bad. Not even sexually I just want him to want me and it's bothering me so much I just don't minnow what to do
