Need advice please about my boyfriend?

I told him I was on my period last month and this month. I tell him every month when I get my period because they just get so bad for me to the point that I faint and I throw up sometimes from them (it’s truly awful for me ) I sent one text to him this month just saying that I had started my period and that was it and then he treated me terribly, he told me to “ suck it up and deal with the pain” and he also called me just to tell me he didn’t want to hear about it ( it was completely out of the blue ) So I need advice about him and how often is it ok for me to be telling him and be bringing it up to him? Him and I are both 22 and this is the only issue I have but other than that everything is fine. If this helps him and I have been dating since senior year of high school we know each other from in person, and throughout college ( but we’ve been long distance in college) since we ended up going to separate schools.
