Boy Drama

Danni
Me and this guy have been talking for a long time and I took his first kiss to his virginity.  But after we had sex he wouldn't talk to me for two weeks then ended our fwb. About 2 weeks after he texted me saying he missed me and couldn't stop thinking about me since he ended it.  We started talking often over the phone and he asked me out on a date on a Wednesday but by Friday he forgot so I was being alittle petty about it on Friday but eventually got over it. Afterwards we didn't talk until we got back from spring break and had a little 'Netflix and chill' but no sex. Afterwards I would try to talk as friends but he was being a jerk but whenever have a fling he would be all flirty but today he was totally acting like a jerk to me and it kind of ruined the rest of my day 
Do y'all have any advice on what to do about how he acts or what I should do?  Because I don't know what to do or how to respond to what's been happening
