UPDATE Theres a rumor going around that my bf isn’t actually military

This is long but please read all the way. I met my bf at the grocery store we were both working at over the summer. I just turned 23 and he’s about to turn 22. He (said) he joined the marines right out of high school at 18, and was honorably (im assuming) discharged around a year later after an incident where his squad was ambushed and he was really seriously injured (im sort of paraphrasing, but thats the basics). I thought he was discharged from his injuries but he says he lets people assume that. He says the real reason is because after the incident he failed a psych test so badly due to ptsd, and he is really ashamed of that fact. We are dating in everything but name right now (i got out of a long term relationship not too long ago and asked him to wait to make it official out of respect for my ex). I only worked at this store for 6 months in order to make money for grad school. He helped me through my breakup and supported me with my dad who was going in and out of the hospital. He is the only person i have ever even had an inkling about marrying. But before i went to off to grad school around mid August, my brother and our friend (both of whom also work at this grocery store) sat me down and said that there is a rumor going around the store that he lied about being in the military. That our store manager spitefully told our friend theres no record of his military service or a record of leave of absence in his employee record (my bf has been working at the grocery store chain since he was 15, at various stores).There is record of his injuries, but my friend says that theres a rumor those are from a car crash. A girl at our store says she went out with my bf but broke up with him because she found out he wasn’t really military (shes supposedly National guard). But this girl has a reputation of being crazy and a little stalkerish, even my brother and friend say so, as well as everyone ive worked with. And my bf says they only hing out once and then next thing he knows she is telling the whole store they are engaged. So she could be a pathological liar, but idk. Now heres the things that dont make sense. He has told me some of the stuff that happened to him. Both through text and in person. I helped him through the 4th of july because the fireworks triggered his ptsd (i did this through texting). His pain seems genuine. And ive seen his dog tags, though i know you can have those made and just put the right info on there yourself. But he just got his 5year pin for working at the store, but if he had been working for the company since he was 15 and hes almost 22 that math doesnt make sense unless he left for the approximate amount of time he was in the military and rehab for his injuries. He also has never claimed to be anything other than a normal marine (no special forces or high rank or anything), which a lot of impersonaters do. But He doesnt talk to me about what happened anymore since we started dating. He asked me not to mention it anymore and that he regrets telling me in the 1st place. He also said never to bring it up around his family because they cant handle what ge did or how he changed. His dad apparently kicked him out of the house for a while after he returned home because he joined against their will. So i cant ask them and its making it seem like the rumors are true. And my family keeps telling me to stay away. I told my brother to request his military record under the freedom of info act because this is turning into he said she said. Im just waiting for a reply, but this is the second tome we sent in a request ( we havent heard the back from the 1st one in 4months). If hes not military we will get a response back saying theres no record. It is killing me to wait. If he is who he says he is my soul mate. If he isnt then the man i love is a sociopath and never existed. I cant bring this up to him because i have a feeling he’d go off on someone at work and get himself fired (i would too if someone denied my service and the worst moments of my life). But every time I bring up the military or try to get him to mention some form of id or formal proof of military service he says he doesn’t want to talk about it. He says he only used the medical benefits once and that he prefers to do things on his own. Im in love with him and we talk every day. If he isnt military im leaving, no exceptions. This whole situation is just killing me.

UPDATE: I confronted him. He admitted he lied. He did complete basic training but right as he was about to leave for his deployment he had a panic attack and was discharged because of it. His best friend who he enlisted with went and died overseas. So He lied about how he got his injuries and the fact that his best friend died in front of him. He said he regretted lying to me the moment he said and that he did it to try to cope with his “failure”. He begged for a second chance or a month long break, even said he would tell everyone he lied. But i said no. It broke my heart.
