<human>: Hey everyone, recent development, had a falling out with a girl I have been seeing for about 4-5 months, I have been on the fence about a relationship basically the whole time I was seeing her, so I wanted to get it casual and low key, long story short, shes a little more attached than myself and feeling have been hurt. 

So she left for cadet army training at Fort Knox for a month and we have been on a break for a few weeks prior. A friend of mine has been touring in a band for a couple years and makes a pit stop in her home town and invites me out to the beach for a day trip with her and her friends, I accept, have a great day, brought a watermelon for everyone. The group makes plans to eat at this mediterranean restaurant, my ex calls after we are finishing up at the beach and immediately starts questioning me about where I have been, with who, and why I haven't made time to council her on a bad day of training... 

I told her I didn't really have time and that we were about to meet up for eat dinner... OK, so then shes posts a photo IG, with both of us on it, and the caption says in short - "fat" "badsmile" "loser" "cheated on me while ive been at ft knox training for army" "asshole". Ok Ok, little overreaction but nothing to bad. Now she has giving my number out, I get text about penny stocks, calls from unknown numbers at all hours of the day. I mean I'm kinda at a lost of what to do... I was to retaliate an IG post but at the same time I'm not trying to get in a pissing match with such a loose cannon.

What can I do!?!?

Can you condense the text into three sentences or less?
