did I mess up a good thing?

I started having sex with a guy who is super sweet, and honestly a really nice guy. But I just got out of a 2 and a half year relationship where I was treated like crap (where my SO wouldn't come home some nights without legitamite reasons why, where he would leave for multiple days and ignore my calls and texts, where he would make me feel stupid and crazy when I got upset about him for ignoring me, and finding girls belongings in his car). I don't trust men because all the men in my life have treated me horribley, my father left me and my mother and treated me horribly,and I was mentally and physically abused by my step father... I feel like guys only want one thing from me, which is sex... I've come to the conclusion that instead of getting my heart crushed again and again by putting my feelings out there for a guy, I would just give them what they want, just sex... which I don't have sex with multiple men, I just find one guy that I'm happy with and I don't sleep with anyone else or talk to anyone else... but this new guy, I feel like he wants something more. When we decided to have sex he wanted to stay the night with me and stayed the whole next morning too, we watched movies all day and cuddled on the couch, I had fun and was comfortable with him... until I mentioned that I had surgery on my ovaries and he looked at me concerned if I could ever have babies... and then when I made him dinner and lunch he stated I would make a really great wife... we've been talking everyday and he calls me baby and wakes me up with good morning texts... but I texted him back this morning and told him "that it was okay if he didn't want to text me everyday that he could just text me when he wanted sex and I would be fine with that" his response was "really?" And when I tried to explain that I was really okay with him just texting me when he wanted sex he never responded... I'm not a slut, I don't sleep with multiple men... this is the first guy I've been with since my ex... I just don't want to get my heart broken... but at the same time I don't want to make this guy run  away when I tell him that he can just text me when he wants sex... I need help not making this guy run away from me because I like him... I don't know what to do my heart is pulling me in multiple directions and I just need advice
