Rant about boyfriends

So, i dated this guy for a while, and a month into our relationship, his mom passed away. i was there for him for the next 7 months. and i realized i needed to take care of myself more due to me getting suicidal thoughts again.(i’ve struggled with chronic depression for about 3/4 years now and ended up in a mental hospital)

we got pissed and would would talk shit in the hall after he told me i never was his type. and recently we got back together. he has this friend who obviously has feelings for him and he went on a date with her, not knowing she intended it as a date, and had her over a couple times.

he dumped me last week and told me he wasn’t ready. i took a look at insta and saw a post dedicated to him making it to state and in the caption it credited her to being his best support system. and i got no credit. when i see them together they’re always touching. it really pisses me off.
