I need some advice: I agreed to a no strings attached relationship with a man whom I've known for a few years. He used to be a frequent customer at the supercenter I work at. We ran into each other online after he and his girlfriend broke up. I made an offhanded comment that single wasn't so bad that I enjoyed it. And not long after we started texting. He was really nice and I liked talking to him. We agreed to no strings... he would make offhanded comments about taking a nap together or a bath. I wrote up as sexual but he said it wasn't... But then would say "no strings right?"... We hooked up and he made sure that I got off. The next time he asked me if I knew why and I said "so you could me again" then he said "so you'd come back".
The next time we just hung out and the next time he hand fed me afterwards it was a while before we saw each other in that capacity again due to a family member staying with him but we texted everyday... and at one point I'd locked myself out of my car and he without me asking he came and got it unlocked. Then one night I got snowed in town rented a hotel and he came and we hooked up and he stayed but slept in the chair. The next morning he scraped the ice off my windshield. The next time was sort of intense.. And I ended up giving up a lot of control... which I normally don't do. And text convos started ending with kissy emojis from him... And I realized that I needed to step back and make sure I wasn't getting too close... because it'd be easy he made me laugh and we could talk for hours...
Well I went out on a couple dates with someone. But when I had a nightmare I texted my no strings guy out of habit (?) And we started talking again... just like before. The last time we hooked up I stayed the night he gave up his bed and slept on the couch though. Said he hoped I didn't get offended but that's where he'd been sleeping anyway. I ended up getting cold and he went and grabbed a blanket off the couch and covered me up. The next day he texted me and ended up making the comment that I seemed to have slept well (which I did) and he texts me to be careful...
This is new to me. I've done relationships and no strings and neither was anything like this. What is going on here?
