Serious Relationship Question: Boy vs. Other Boy

Hello, I am here to ask a question that I do not currently know the answer to. This is a relationship question, dealing with two guys. I have always been used and abused and a bit over half a year ago I found the -perfect- boyfriend. Caring, loving, sensitive, and all around wonderful, though we don’t share a lot in common. Being a bit older (young adult), I could really see myself with him long term, and it is wonderful. Around end of summer though, I went to this meet-up full of people who had interests like me, where I met a really awesome guy. We chated forever as good friends, and me always telling ihm about my wonderous relationship and him always saying how he was jealous of my boyfriend for finding a girl like me. Eventually he confessed his feelings for me, and then I began to realize I had feelings for him too, but shook it off as nothing. Recently, I went to his town to visit him and go on a huge shopping spree. We spent the weekend as great friends, but eventually he kissed me and then it turned into more (but no sex). I came home a few days later, and told my boyfriend about it, I felt horrible for hurting him but in all honesty, and this may sound bad but, I didn’t feel guilty for doing what I did. My boyfriend was very happy I told him what happened and now we are all patched up. Unfortunately, though, I can’t stop thinking about this other guy. I can’t see myself with him long term, but sometimes I just want to be near him because he makes me feel accepted for what I like and do. I’m afraid I’ll get more attached, and sometimes I want to avoid him to keep the relationship I’m in perfect but it’s like I crave the other guy, and he really cares about me too. So what am I to do? I’ve thought about trying to have an open relationship with my boyfriend until he gets out of school and then being just us and serious, but what if I get attached to the other guy? I could always try leading a double life but thats dishonest and I am too honest to do that. I’ve lost some respect from friends on this but feelings are feelings, you can’t prevent them. What’s the best thing to do? Who should I go for? Please, give me your insight.
