My boyfriend sometimes likes to go out to drink with coworkers, mind you he is the only guy and the rest are girls..

I don’t have an issue with that I’m not a controlling person.. anyway one of his coworkers posted this photo on Snapchat and one of the girls is hugging and kissing on his cheek..

I got called crazy and psycho by his coworkers and him Bc I was upset about this.. am i over reacting or do I have a reason to be upset? I also recently just found out I was pregnant and I’m currently 8 weeks..
