My girlfriend (W/17) and I (M/18) have been in a relationship for 1 1/2 years now, after around a 2/3 year into our rel. I did something really stupid (I texted with other girls eventually broke up with her and slept with two other girls in the time when we were broke up. Also in that time she got hit by a bus and had some injuries, nothing really bad but still traumatizing. We came back together after two months).

I am a different person in those things but still, the trust is gone and trust me I regret everything I did every day. We had many fights about stuff like me talking to friends who I know since 5 or 6 years - or even longer (girls) etc.

The Worst part tho is that she lately feels really alone and that she has no one else but me. She has many troubles in her family and barely to no really good friends - I mean she knows people and talks with them, most of them know her through me tho. And the ones she likes and wants to be better friends with (mostly girls in our "clique") don't really take her into the group - like they always go out together but barely invite her to come along. Also, shes always referred to "(my Name)'s - girlfriend).

Then there is this person on Instagram that sends her messages no one wants to get (something along the lines of "you look so ugly you should hang yourself, your boyfriend is stupid for choosing you - you should've died in that bus accident" I know that is hard for her and lowers her self-esteem by ton's, even tho she is incredibly beautiful - like for real.)

I just don't know how to help her anymore or how to get her mood up... I thought about talking with some of the girls and asking them why they don't really take her along?

It's getting worse and worse day by day... she is really scared that she won't be happy anytime soon again - if ever. She is just always really sad and to be honest it hurts our relationship.

If anyone knows how I could help her to "get" more friends, or get closer to the people we already know.

I also told her that I would recommend a psychologist because I feel like it is getting pretty serious - she said no...

Please help me, I will try to answer any question and I'll be happy about any, serious, answer!

Kind regards - Bedmansdog

(Yes I know we seem pretty young for those kinds of problems and that friends are complicated in that age but still, her sadness is real and it is getting scarily serious.)
