Boy advice? Possible trigger warning

I’ve been talking to this guy for 2 months and we’ve been through some stuff so far, he ended up letting another girl give him a blowjob on Christmas eve and I ended up forgiving him and giving him another chance.

Then on January 9th stuff hit the fan. My grandfather shot and killed himself.. the weekend before was my grandmothers 1 year since she passed and the day after that was my other grandfathers memorial. I also have started cutting again, restricting food, and just being bad to myself.

I’m just falling apart really and I don’t know what to do anymore. I don’t know what’s going on with us anymore, he barely talks to me, when he texts me it’s really short and I just feel like he’s losing interest. Idk??
