Would you consider dating a guy like that?

I know to each their own but being like that, Will it affect the relationship in the long run?

I have a 56 yrd old cousin who was divorced many years ago. After her divorce, she dated but not so much but never stick long to any guy he dated or seeing. My cousin has a peculiar behavior, she gets offended by non sense stuff, she is a foul mouthed person, she is very sensitive in things, she likes to criticize often to relatives or even friends about things. On the other hand she is very social person, she likes to attend parties, hang out, make pranks, joke with people, loves to take trips locally and have fun either with friends or relatives, also likes to travel overseas, when she can.

Many years ago when my sister got divorced (also) my sister (who is about to be 56) got divorced like 23 years ago, her former ex was a very anti social person, he did not like to attend family gatherings, or being surrounded by people, anti social, have fun with the family, jokes, etc Besides other relationship issues, my sister did not like that part of her ex, being so anti social., always bitter it seems. So back then my cousin criticized my sister about my sister ex about being that anti social and bitter and my cousin even was glad when she got divorced.

Fast forward my sister got married again with a former classmate from high school like 20 years ago. Her new husband is the total opposite, he is social , likes to make pranks, travel, have fun.

Back to my sensitive cousin. Like one month ago she started dating a guy, coincidentally it was a former classmate from high school as well.

He is a physical education teacher and my cousin works at a mic lab at a hospital. Well it turns out that my cousin new guy is the same: anti social, do not like pranks or jokes and no fun. I mean my cousin criticized my sister for being married to a guy like taht and now she is dating a guy exactly the same. And my sister now says well for now on if we arrange family gatherings I won't invite our cousin boyfriend, cause he does not like to be surrounded my people.
