<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey Reddit, my boyfriend and I have been dating for 6 months and have started to have some real issues lately. His interaction with his exes makes me uneasy. 

The first ex, was a girl he met while he studied abroad. They had a thing and then moved back to their hometowns. This was two years ago, and they text every single day, sometimes even called. He would text get while literally being naked next to me in bed. He told me I had nothing to worry about. However, I had a bad feeling in my gut. I didn't even snoop, I was watching a video on Facebook with him when she chatted him something very flirtatious, reading "oh so that's why you're attracted to me". He told me I was completely misunderstanding. It made me feel so crappy.

Now, he planned a trip to go to a concert with another ex girlfriend of his. They dated pretty seriously, and in all honesty I felt jealous. I didn't understand why he didnt include me at all. The concert was 7 hours away and they drove earlier today. When I would text him during the day, he was very moody and being snappy at me. I tried to let it go.

However, this was my mistake. My mind kind of ran wild. He didnt text me all night. I finally texted him at 2 am, asking how the show was. He gave me a quick response and I then told him I was a little upset with him right then. He told me I was being absolutely ridiculous and he was not going to respond to me. I don't know why. I was emotional. I called him like 5 times, which was so stupid of me. He's responded now, telling me I'm "batshit crazy" and I don't deserve him. 

Reddit, I'm just really having a hard time. When we're together we get along great. Maybe I'm insecure, but I don't how to fix it if I am. He told me he'd talk to me the next day. I don't know where to go from here. Please help, and please be honest with me if I have done anything wrong.
<bot>: boyfriend has questionable interaction with his exes. I got nervous and acted a little irrational. He went off on a rant of hurtful words.
