<human>: Been in a relationship for 5 years now (living together for 4). Sex life has been neglected the whole time (minus the first few months), which has driven me crazy. It feels more like we're a sexless, old, married couple, which I've grown mostly accustomed to. We had bad fights early in our relationship, and he has cheated on me. The past year or two of our relationship has been peaceful but lacking all passion.

However, a huge fight over nothing last week (both of us acting like children) led to me flying across the country to stay with a friend, who I have feelings for and we ended up bonding very closely. I've been in enough early relationships to know the adrenaline from falling in love, so I'm trying to keep my head around that. This person deeply wants me to stay here with him and/or have a long-term relationship until we can be together. He is an innocent, passionate guy, and I do feel very strongly for him and think that we could be happy together. I feel like he reignites me and makes me want to be a better person, not because it's new love but because of his personality. 

The differences between my boyfriend and this guy are huge - my boyfriend smokes, drinks, does drugs, and is a very negative person, which is much of the reason we fight. The guy out here is clean, responsible, and his interests line up with mine. I sit on the fence between the two personalities - I can go either way depending on who I'm with. 

I'm flying back home tomorrow, to my boyfriend who I'm not even sure missed me. This sounds terrible, but after this week I feel that I could see myself getting over him. I didn't feel like that before I left - I just wanted to get away to find some clarity of mind. I feel that the bigger reason I'm going back is simply that I love my job and don't want to abandon it.

As I said, I'm returning home tomorrow. I'm unsure of what I should do from this point.
