What the hell kinda situation is this??

I have no idea what kind of situationship I’m in, but hopefully you all can help me out. I’ve known this guy since high school and he and I were good friends, but just that. We talked every now and then once we graduated but we reconnected recently since he’s graduated from college and I have too. We started back talking but then we met up a few times and ended up having sex.

We both said we didn’t want a relationship because he had gotten out of one earlier that year and I did too but the connection was undeniable. We have great conversation and our morals and values align really well. We have similar interests, etc. He wanted me to meet his mom and go on this trip with his family. I pulled back due to being fresh out of a relationship and scared to put my heart on the line. So we ended up falling off for a month or so and reconnected again.

Since then he’s running his own business and doing other jobs. So he’s always busy and he isn’t the greatest texter. We’ve talked about a relationship and he said he wants to take things slow but I found out he had sex with someone else. Since then I told him that if we were to continue our “relationship” that he couldn’t do that and it’s only me or I’ll leave. he told me he can do that and since then we’ve continued to see each other.

He’s always telling me he has feelings for me and how they’ve grown stronger over time but I also think he’s scarred from a previous relationship. Last time I saw him he apologized for giving me a hard time, but he really likes me and he wants to take me out in a few weeks and has offered to pay to get me a massage. I don’t know how to interpret all of these mixed signals. Is he actually trying to take things slow and wants a relationship or is he just stringing me along?? Help! Sorry it’s so long.
