What going on with this guy?

[Miss]

I dated this guy for three months. We recently.ended things. I.went on a date with someone and I got a strange text from my x. I replyed and next you know we were arguing. Then I.got a text from.him.saying that it im coming over. Then I.got a call from him saying im in los vegas On vacation and my.girl.was the one texting you and she coming over today to see you like a threat but keep in mind I dont live in los vegas its in a different.state. Which is odd. Another thing happen he called me wanting to.hang out and said never mind. Then I got a text saying do.you wanna you know when are you off. I reply and he told me not to text. Later he said he found a different girl and moved on. one thing I remember one time we were dating he got a phone call from a guy. He told me it was a girl. He said he had alot of gfs. He seem pissed and didnt want to continue are date. he told me he had an eye infection.was in the hospital was two week.
