I don’t know how to break up with my boyfriend in this situation PLEASE HELP

I’m going to start by saying I know I haven’t handled things well, this is my first ever attempt at a relationship and I’ve definitely made mistakes but I’m trying to figure out how I can deal with this and end it with the most minimal damage.

Context: I am in my early 20s and I’ve never had a boyfriend before. I was going through a rough patch in my life and thought trying out dating would help (first mistake). I met a guy online and we’ve been on roughly 7 dates. I am beginning to realize I don’t have feelings for him. That feels like a normal time frame to truly know if you have chemistry with a person and it would normally be fine to end it and say I just don’t think it’s working, but this is the kicker…Valentines Day…I know that if it wasn’t for the elephant in the room of the holiday he wouldn’t have asked me to be his girlfriend yet, given the fact that we had only seen each other a total of 6 times. There’s a chance he might’ve without the holiday but I personally think it was way too fast, but 2nd mistake…I didn’t say that!!! I panicked and I agreed even after the most awkward Valentines date ever. We hardly had anything to talk about and that problem has continued. We never have anything to talk about other than small talk and it’s driving me insane. I’ve had several major life events happen recently and he hasn’t asked about one of them, instead he will just ask “so how’s work.” He’s also never made me laugh. We just aren’t compatible and I know that now. It took me so long to realize because with it being my first relationship I thought all the problems were my fault and that I would get over it and I would get over the anxiety of seeing him, but it hasn’t and I’ve realized why. But now it’s been a month and I know I want to break it off but he thinks everything is fine. It’s so hard because it isn’t like we’ve been in a real relationship. We haven’t even hugged….I know communication is important and you shouldn’t blindside your partner, but what do you do when it’s this early and you realized you shouldn’t have agreed to be their partner? We’ve literally only seen each other in person one time since Valentine’s Day because of the distance. If I had understood my feelings sooner I wouldn’t be having this problem but I feel so stuck now and I just don’t know what I’m supposed to do, please help 🙏🏼
