Period cramps N support

So my bf went out yesterday ALL day with his homeboy (sat through him getting his hair done) and then went to link with another until 6-7 in the morning. I really wanted to go off but I feel like if your gf is in pain and you’d rather chill with two men until the wee hours of the moment your character is there plain and simple for me to see. Am I jumping the gun? Or do you see how I can think this? What are your thoughts?
