In my experience, anyone who is all in before there's even a relationship is someone that I need to run from ASAP. They're not interested in me, they're interested in a relationship.

Seriously, one month and not even a couple and saying things like "I want to spend all of my time with you and make you happy."? Especially if he's said those things after you've said you want to take it slowly, too. Taking it slowly isn't just physical, and it absolutely sounds like he's doing the "Yeah, I understand and am totally accepting of it. By the way, when? When? When? When?"

So maybe your gut is seeing all of these red flags? I know I've beaten myself up and given a guy multiple chances because he was so nice and I didn't get why I didn't like him. ... Then one date he didn't let me see the menu and it finally clicked that I wasn't interested in him because he kept saying little things to push me towards a relationship despite my resistance. It was like "Wow, that was kind of inconsiderate. Oh. Ooooohhhh."
