Seeking advice
Me and this girl have been together for 6 months after I was in a traumatic life with my mom after my dad left when I was 4 we did good until the overthinking and me thinking she is everyone else interfered and the last night before she ended it to say I need to be better and work on me for one month I logged into her snap and she was dancing with her friends and a guy she wasn’t with I seen and got insecure and called her and tried to see if she was okay she asked for me to wait until she got home I called her friends who hate me on her account because of what I saw and they said that I need to leave her alone and their saying if she talks to me they won’t be her friends because of mine and her situation being toxic so they said to leave me and she wants me to get better but snaps guys and says she don’t text them or see them so it shouldn’t matter because we’re not together so I got over it I just want her back what steps can I take to remember to breathe and not be toxic considering my situation it’s so much I forget and take it out how can I trust someone
