Is that rn the reason he’s changed?

I’ve been dating my boyfriend for two years, coming up on three. The first two were great, AMAZING, I saw him all the time.

This past July he lost his mom, she committed suicide, and he disappeared for two weeks. The first day of August I almost drowned and I feel it was a lot of trauma for him, it was also his last year of college this year.

Since then he had gotten more distant, to the point now I wonder if we are dating, as I will hear from him every 5 days essentially. He also gotten mean, trying everything to push me away and when I leave he says he messed up and is sorry.

I don’t know what to do,
