<human>: Provide a brief overview of the text.

Dear reddit,

My boyfriend and I have been dating for nearly 3 years. He's always expressed, even to this day, how he's completely in love with me and how he's crazy about me etc etc. HOWEVER he is in a big party fraternity and early in our relationship, although he didn't cheat on me, he did flirt with a lot of girls for ego validation and attention.

Fast forward to yesterday- my bf is on vacation to Alaska and he hasn't had service because he's on a cruise but the few times we can talk, he tells me he has a gift for me. I wanted to reciprocate that, so I was looking for different gifts I can get for him. He is a musician so I wanted to get him something related to music. I couldn't call or text him cause he's overseas so I decided I'd maybe get some clues by going on his fb (he gave me his password himself so I thought he has nothing to hide). I briefly skimmed through a convo with his best friend whom he always talks with about music, and found recent conversations where he's obsessing about other girls and talking about "the struggle" of it. And how he hopes that the cruise he's on has unattractive people because he doesn't want to get tempted and he's extra flirtatious on vacations.

I already have trust issues with him- I used to find so many flirtatious texts with other girls in the past (not anymore), but this makes me lose all faith and hope in him. Maybe I am overreacting- but that is why I am on here asking for advice. To me, I think: Does he need to have ugly people around him to want to stay loyal to me? Is that what it really takes? I thought we had a serious relationship.

I don't want to be in a relationship where I am always on edge about whether or not my partner wants to be faithful to me. I want to know for a fact that he would love to be faithful to me just because he loves me. Please tell me your thoughts on this, and be honest- I hate constantly feeling like this with him and I am considering breaking it off.
<bot>: Thought my bf of 2.5 years was serious about me, he acts like he's crazy about me but his conversations with his friend proved to be different than what I would've expected.
