He randomly started ignoring me. Did I do something wrong?

I recently finally got over my bd after years of tolerating less than i deserved. I have been open to dating and finally decided give this guy the time of day. He reached out saying i'd like to get to know you. I asked him in what way was he wanting to get to know me, as just friends or something more? He said he'd love to be my friend and possibly something more. I messed up telling him i was cool with being friends as I'm not ready for a relationship just yet cause ive been hurt, have trust issues and healing but as we get to know each other more, we can maybe progress into trying for a relationship. He claimed he wouldn't hurt me, he's going work to gain my trust, he's willing to be patient with me, he deserves love too blah blah. So at first, we were doing GREAT. Would hang out, game together, talk nearly every day until we first tried to have sex. He wouldnt stay hard for some reason and i asked him if it was me and he claimed no, he was just nervous or needed fruit/wine to get more turned on. So next time we hung out, we had that stuff but still, wouldnt stay hard. After we hung out again, i asked him again is he sure it isnt me cause we got the stuff he said he'd need and still didn't stay hard. He claimed it was still just nerves and been awhile since he's had sex. I asked how long ago and he said 8 months so i asked if he had trouble getting hard with the other girl and he didn't want to talk about his past. Ever since, he's been acting different. Each time we were supposed to "hang out" something came up and we never did. Was supposed to see him last weekend but he stood me up again so i told him i gave up and he basically said dont say that, he just has a lot going on. Days went and didnt hear anything so i just said so we just done talking?All he said was no we're not so i just told him okay. Days go by again, still nothing. He then sees a nice picture i posted and just said you're so fine and i just told him lol thank you. He then said you're welcome, told me be safe and said I love you. ( ?????) I didnt really know what to say to that so i just said i miss you and he said i miss you too. Fast foward, messaged him monday asking if he still possibly wanted something more with me, he said yes I do. I told him then show me that and to see me that night, he opened it and never responded and we haven't said anything since. I don't get it?He did all this talk of he'll work to gain my trust and wont hurt me just to do this like it doesnt hurt me in some way?Surely i was gullible and he had me fooled and it sucks bc i really started to like him. I dont get why he wouldnt just tell me he doesnt want to talk anymore like he wasnt given the opportunity to speak up to say that but he instead said otherwise. This isnt showing me that we arent done talking and that you want something more with me. I sorta want to try to hang in there bc maybe he does just have a lot going on and he just has a bad way of communicating or should i just delete him from everything and be done?i cant help but think it was my fault pushing the whole why cant you get hard thing. I thought it was a reasonable thing for us to discuss but i guess not cause we were fine up until then. Wonder if had i just not said anything if we'd be okay now.
