confused and angry

So I met my current boyfriend online and we've been together for some months now and things aren't the absolute best because he's hardly around due to his job. he's a task force officer and never really has time to spend. when we do see each other it's great but it doesn't happen often. about 3 weeks ago, I got a text from my dad and a friend that I haven't talked to in a year asking me for a picture of the man I'm with. my dad met him and I told this friend about my relationship after reconnecting with her a few weeks prior. it was too weird that both of them asked for a picture so I just straight up asked her if there was something I needed to know. in a nutshell, she said they talked a bit online, met up and had sex. she was able to describe everything about him and I didn't tell her anything about him except what he does for a living. when I confronted him about it, he claimed that it was his brother that was driving his car that night and not him. he claims that everything she knew about him, she was told. It's such a mess now and I really don't know what to believe. at this point I don't trust either of them. by the way, he and I have financial obligations too. I'm feeling rather stupid at this point and he hasn't made any time to talk since that night... It's taking a toll on me and I'm tired of waiting for him to resolve this. what should I do?
