I (21F) caught my boyfriend (23M) talking to himself through a messaging app.

i (21F) went through my bf of a year & a half phone (23M) and found out that he was texting himself through a messaging app.

he has a number saved in his contacts as his “supervisor”. instance #1. during the holidays, he told my family & i that he was working “on call.” he said he was going to text his supervisor and see if he could get off earlier. 10 minutes later, he shows me his phone and shows me messages of this “supervisor” approving his request. great, now we can actually relax and i don’t have to worry about you leaving any second. instance #2. we’re on the train together, but the train keeps getting delayed. i turn and say “i wonder why this train keeps getting delayed?” 2 minutes later, he shows me messages from his “supervisor” explaining why the train was so delayed. i thanked him for being able to help me understand the issue and we continued on our route.

and then fast forward to a couple weeks ago, i go through his phone & find out that these messages are not coming from an actual supervisor. this whole time, he WAS the supervisor. so he was never “on call”, he never had to send a text to get “off call”. he had been texting himself back and forth for months and he just recently stopped after i confronted him about it. i’d like to note that i was also not perfect in this relationship. i don’t want to make it seem like he’s the bad guy and i’m the innocent victim. however, this, i feel is next level. doing this takes serious dedication. and honestly, it’s scary. i would’ve been forgot to text myself back within 2-3 days. in one of the messages, he expressed to his “supervisor” that he was sick. & i remember being with him and taking care of him during this time. his “supervisor” (him) replied and said “i hope you feel better, make sure you stay hydrated and get rest.” my brain cannot comprehend this. ://

i asked him why he did this. his reasoning was that his parents don’t believe that he’s at work when he tells them so he fakes messages so that he could show them as proof. sounds like bs to me. that excuse would’ve just barelyyy been believable.. if he didn’t include me in the lies. he apologized for including me in it and he says he wants another chance to do better but i’m afraid that this other chance will just be another cycle full of lies. if he’s willing to go THIS FAR with little to no motive, how far is he willing to go when he has something worth trying to cover up? he also admitted that he’d do things to try to impress me. i think he may be having an identity crisis idk. he makes me feel bad for choosing to walk away but i keep trying to explain to him that this isn’t a normal situation that people go through all the time. my brain cannot find a reason to validate this behavior. also, i’d like to note that before all of this, i also caught him posting a video on social media pretending like it was him when it really wasn’t. but, i chose to move on from that situation… i feel very disrespected. i feel like i welcomed a stranger into my life. i feel like he knows everything about me but yet, i don’t know anything about him because i don’t know what was real and what wasn’t. if this were you, would you stay with this person? he seems very apologetic & he’s an amazing man aside from all of this but, this really really threw me off.
