<human>: A bit of background.
We've been dating for 4 months and we've become incredibly close, already dropped the L-bomb and whatnot. Only a few weeks ago he told me that he loves how much time we spend together, and he hates not being with me. Then, about 3 weeks ago, I got the birth control shot because he didn't want to have to use condoms anymore.

The shot has made me incredibly moody. I do my absolute best to keep it under control, and I always apologize when I have a severe mood swing and do something stupid or mean. It also affects my anxiety disorder, making my panic/anxiety attacks much more frequent.

Now, for my question. Am I wrong for being upset that he has now been deliberately trying to get rid of me a couple hours into hanging out? He ditches me for his friends, which he has never done before. He apparently doesn't "hate not being with me" anymore. I really don't know what to do, and I'm pretty upset with how he's treating me after I got the shot for his personal preference. 

What do I do??

Can you condense the text into a few key points?
<bot>: I got the birth control shot for my boyfriend, and now because of the side effects he wants to spend a lot less time with me. Am I wrong for being upset about this and what should I do?
