TL;DR am I experiencing gaslighting?
Last night at my 20 year highschool reunion my husband stood off to the side all night while I tried to keep him included. I asked him if he was bored and wanted to go home. He threw a napkin on the table and walked off. He told me I was nagging and annoying. My intention was to make sure he was okay. He then told me it was because I was drunk. The thing that really bothers me is that he said he wasn't and only had three beers. I watched him drink about 12 beers. He now says I have a drinking problem and even told my parents. The thing that makes me second guess this is that I stopped drinking and went to bed. He stayed awake and eventually passed out in a chair on the patio outside. We both drank too much but why am I the only one with the problem.
Another incident was when he drove my car and it came back with two large dents. I asked what happened and he said someone hit him. I did not know so I accepted it and said please be careful where you park. I've never had a scratch or dent in the car I've had for 3 years until he drove it. He then said he was bored with the conversation. I just wanted him to apologize and say he would be more careful. Maybe he didn't know but I feel like if it was in his possession it was his responsibility.
Is this what gaslighting is?
