<human>: Can you give me a shortened version of the text?

Me and my friends, bot guys, both 19,been friends for 10yrs, got into a little tiff the other night. I'm home for the summer back to me my first year of college, and he just graduated high school.

Earlier in the day, we had talked and I had asked him what his plans were for the night, and he said he had a softball game but suggested we hang out after dinner, I agreed.

Later that night, around 5ish, he invites me over for dinner, and I decline, saying that I had asked my parents to make a certain dish that night, but still offered to come over after. He said don't bother, then tested me later saying that was an asshole move. I said it wasn't, I was going to be home when my parent made a dish I requested, and the argument devolved from there.

He cited that he just wanted to give his mom come company tonight, and that he's been over at my house a lot this summer (his gym is 2min away, so he swings by afterwards often.) he then said I wasn't putting any effort into the friendship (I took him camping with my family that weekend,) and that I never try to make plans with him, only the other way around. Then said count me out.

I told him that I hardly have plans and he knows it (my friends are all over the country for the summer) and that he often does, but I still ask him what he's up to. I then agreed to come to dinner (poor move) and he said no don't, I need to cool off.

Before when I've declined similar invitations for similar reasons, he's gotten mad as well, even though he does the same thing all the time. He is leaving for 2 years (jesuits) in a week and a half, so he might be anxious, but I don't think that excuses this.

He's always been a manipulator and I haven't realized he does it to me till just now. How do you deal with emotional manipulation like this? Using his mother and citing poor effort on my part, when that's arguably untrue? I can provide any other details as well as text transcripts if needed.
<bot>: declined friends invitation to dinner for legitimate reasons, starts using emotional manipulation on me, citing me as poor friend and I caved.
