Breaking up?

Al

My boyfriend and I have been together almost two years( our anniversary is in October) but for the last few months I’ve grown distant and just lost that spark. I tried ignoring it thinking it’s just a tough time in our relationship because I’m working and just started college and he’s working too but as I’m away from him I’m finding my self looking at other guys and girls which makes me feel more than guilty. I love him and he’s my best friend, kinda my only friend since I graduated high school. I don’t want to throw everything away and all the memories. He’s been talking about moving in and taking big steps that I don’t want to anymore. I don’t want to spend time with him or have sex anymore. I’ve come to the conclusion that I may still love him but I’m not in love with him any more ... it’s heartbreaking when it dawned on me but I haven’t said anything. I’ve been distancing myself but he’s so bad at taking hints that something is up. We’ve never had a fight or anything like that before and I don’t know what to do. I don’t want to break up but I know in the end I’m going to have to and need to. That’s what I need help on I don’t know what to do or say. I feel like a horrible person for feeling like this and telling him that’s it’s over out of the blue just seems cruel that’s why I’ve been distancing myself away which probably isn’t a good idea either. I just need help on what to say. It hurts to think I’m going to have to do this and it’s so hard because I feel kinda trapped based on things he has said before like “you’re the only thing i care about” or “I don’t know how I could live without you” etc etc. I just need some guidance please I’ve been thinking about this for months :(
