Leaving my current boyfriend: what to do in this situation (read description I need advice please)?

So I’ve been dating my current boyfriend for just over a year now, and in that time there’s been a lot that I’m not happy with. I do care about him a lot, and I have love for him. However, we don’t go out and do anything together we just stay in his house, he has no interest in doing things with me, everytime I see him his best friend is there with us and we don’t get much time alone together, and he doesn’t like my lifestyle and the fact I like to go out and party with my friends (I’m 22, he is 23 by the way). A week ago I went to a festival and while I was there a guy approached me after noticing I was too scared to go on a ride there after I’d already paid for tickets for me and my friend, he was really nice and offered to go on with my friend if I was too scared, and he would pay for my ticket if I wanted to go on after. We spent the rest of the day together with my friend also just talking and enjoying the music there and later that night he asked if I was single. I told him I wasn’t and I had a boyfriend. But part of me felt bad, like I’d missed out. I felt so guilty about it because I care about my boyfriend, but it made me realise I’m not compatible with him, and maybe there could be someone better suited to me out there. The guy said if I was to ever leave my boyfriend to message him but said he wouldn’t want me to straight away and it would be some time in the future as he wouldn’t want to ruin my relationship or come in between anything. Ever since that night the guy is all I can think about, and I’m wondering if I should leave my relationship that I’m unhappy in and give it a shot? I’ve never been in a situation like this before, but I have a feeling that I can’t ignore. What do I do
