I'm a F26 met a guy M2 (no I was not being a cougar or predator he pursued me first and I kept him at bay for at least a month, he really only took me to one place which wasn't even an official date just a hang out and when he invited me to his place 2 different times to watch anime with him he made me some baked salmon and rice) in November and we got to talking and hung out long story short we admitted feelings for each other and while we didn't get extremely intimate made out heavily and had some forepla but no penetration PERIOD. About a couple days later his cancer comes back (yes real cancer not a fake excuse) in January to mid February he's house bound and going through chemo.

Last week he mentioned he's ready to date since he grew back his hair and could work out again, when I asked if he was ready to date me he said no, I felt hurt and used. He even had the audacity to wonder why a certain woman he liked dated another guy that was just as successful as him only he was younger. But then when I say I need space he gets upset says "wow, really?" Like wtf a part of me feels like he was a player but his ex was his FIRST real gf and they dated 2 years and they were opposites when it came to religion, politics, and health (she didn't really work out) and we both had religion, politics, and health in common but idk he still wasn't honest so I still feel I was the rebound

I realized recently I was his rebound, his ex dumped him in October, we talked in November and confessed our feelings in December. When I look back the signs were there, I asked when he broke up with his ex he just said "within the past 12 months" when I mentioned I thought he was flirting with me he mentioned he was flirting with me and 2 other girls(one of them being the girl who's dating another successful guy), I told him I didn't want to be on an episode of the bachelor so he can remove me from the list. He said he liked me, said only his ex and a platonic female friend were the only ones who had been to his apartment

After all this I blocked him, a part of me feels I took my power back because he wanted to stay friends but I realized he just wanted me in his roster, I just feel kind of dumb because I'm at least a 7/10 and while he was financially stable and had his own place, graduated early with a Bach in economics because he took AP classes in highschool as far as looks go I'd give him maybe a 5/10 he was 6'5 but even one of my guy friends said I could do better, and he has absolutely no interest in me

TL:DR why do guys use girls like this, we actually had stuff in common and had decent conversations, he even made me salmon and rice? Also why would he have a poster size photoshopped picture of himself in a MLB uniform, he wants to be a pro because he played before but why the photo? Also how do I move on from this, we still go to the same church and while I could go to a different Sunday school to avoid him I like the other friends I have there...
