Search Results: is it ok to sleep with other girls

Was hit on at a bar by this guy I went to school with. We exchanged playful banters and flirting hardcore he was drunk I was drunk said some pretty nasty ;) things he kissed me before I left. He messaged me on Facebook the next morning and gave me his number. We text for a while and stuff. Nothing major. Then the next weekend we saw each other at the bar again. He ignored me was talking to other girls would walk over abd talk to ne for a while then would go off with someone then at the end of the night he walked up to me and was like how are yoy gettibg home. Said my ex was picking me up and he was all go have fun with your ex. He called me and was acting like an asshole saying I'm single your single you can do what you want whatever. I told him I like yhe sober him much better he text me the next day and said sorry he was having a bad night. I ended up going over to his house we ended up hooking up. After the deed was done I immediately got dressed abd said I better go. He walked ne outside and smoked a cigarette I said ok I'm gonna go. He told me ok make sure you tell me when you get hone so I kbow your ok. I said ok and left. Text him when I got hone he said are you sure your home I said yeah and he said ok good :) im going to try and get sone sleep. Goodnight :$ and I said goodnight

First off wtf does :$ mean and secondly was he like maybe offended by the fact I just left and thats why we haven't talked? I'm super confused here!!!
