I recently saw messages of my GF exchanging flirty messages to a guy from a year ago when we just started being a couple.

Me (21)M and my GF (21F) have been together for a year now and we’ve known each other a year and a half. I love her so much. We bonded quite well, we had some fights and i would say she is a bit insecure and she sometimes checks my msg and apps without my consent but couldn’t find anything and she gets jealous quite easily when im talking to females, I on the otherhand never check her msgs but i do occasionally get jealous when she hides playing with other guys.

One day i decided to go to her house and chill a bit. we bonded and had a lot of laughs and after she fell asleep i decided to play a bit on her computer. I decided to open up discord. I noticed that she always clears her recent chat boxes so i was the only one on discord in her DM’s. but then one guy suddenly msged her and i couldn’t help myself so i checked, i thought to myself, one time wont hurt, but i was wrong..

JUICY PART <<<

At first i didn’t think much of it. It was just her asking if the guy knew a guy she was talking about. but after i scrolled up i discovered that she had been flirting with the guy a year ago while we were just a month of being a couple. they were both sending flirty msgs to each other and that she would want to sit on him and that she wanted to buy a lovense but was waiting for someone to control it and just them sending out really provocative msgs to each other sending hearts and him calling her “BB” mulitple times and i even saw the guy saying a weird type of “hello” and remembering that she said that weird “hello” to me (basically she used their special “hello” to me) which i was mad about because i remember asking her where she got that from but she didn’t answer me.

At that point i didnt know what to do. i could tell that she wasn’t talking to him that much anymore and i do think it stopped a couple months back. but im so mad that it was a year ago where we just had started being a couple and its been i few nights now and i couldn’t sleep please help.

TLDR
I recently saw messages of my GF exchanging flirty messages to a guy from a year ago when we just started being a couple and now i dont know what to do.
