tinder... dating... mental illness.....

ladies I need advice, I went to this guy's house from tinder. he got me a ride with lyft there and back home. so between that time we was doing 4play and he was playing one of his instruments for me. but here's the problem, I bought us a pizza and he claimed that he got sick from it. in my mind he wanted me to leave but he didn't know how to tell me that without hurting my feelings. so kept leaving out his bedroom several times, so as I was looking for my wallet and my phone because at that point I felt unwanted by him, I seen his wallet and I took a dollar and some change from his wallet. waking up I feel terrible for doing that, that is not my personality but I have noticed that for the past few months I have been acting like a bitch to others. I been feeling like as much trauma that I have been through I have to get back at the people who called me stupid crazy dumb, not strong minded ect..... he was being nothing but a gentleman to me and I feel like I messed up a chance at love. my mom said I guess you want to be alone and bored all your life, based on going through his wallet. so ladies should I text him and tell him what I did (I can easily say I thought it was my wallet btw) or should I not contact him at all? I am not use a man making me feel like I'm special and don't only want sex. we didn't have sex but I had with out it. so what's a girl to do?
