<human>: I don't want to go on too much about our background as he's a redditor too (Names, dates have been changed). We're from the same home town and we met there one summer during our undergrad degrees. We've been together for 6 years, we were long distance whilst we did our undergrad degrees (which was pretty tough) but our grad schools are much closer together now. 

I feel like a reoccurring theme in our relationships is how he deals with his anger. He basically seems to get frustrated with me, but won't say why. Yet he will still act angry which in turn makes me frustrated too. I've not had much of a backbone really and I normally just give in so the arguing will stop. I think this has a lot to do with why arguments have gotten so bad. They happen maybe twice a month but have got more frequent.

The latest argument happened after we both had tough days. We discussed this for a while and I tried to be supportive despite being seriously exhausted. I told him I couldn't stay up any longer, said goodnight and wrote him a mini paragraph saying how much I loved him, other cute stuff, hoping to make him smile a little. His response was extremely blunt. 

This really really fucking hurt. He knew I had a tough day too. So I told him how I felt and explained to him that it was pretty clear something had frustrated him but that it was not an excuse. 

He apologised for hurting my feelings but went on to call me childish, tell me I was overreacting, told me to stop making a fuss over a non existing problem. 

Was I being childish? I didn't swear at him, I wasn't overtly hostile or anything, just said how I felt and how it was really upsetting. He's said it so many times that I'm not sure anymore. This happens all the time. I'm starting to think I might have been in the wrong. I don't really know. Is there a better way to frame how you feel rather than just say it? Who is in the wrong here? I can't see straight reddit.

Can you condense the text into three sentences or less?
<bot>: BF of 6 years says I'm overreacting whenever I tell him I feel upset (specially if its about him). I think he has underlying anger issues. Am I in the wrong?
