Relationships

So my friends with benefits has went of the grid like he has disappeared and I found out why he has disappeared. He has a girlfriend (I did some investigating, he was never going to tell me) but he doesn’t know I am aware and whenever I text to meet up, he always says he can’t. He’s Recently changed his status but I can’t see it, so I am wondering if I am blocked. So should he have told me that he is in relationship or is that none of my business? I shouldn’t have been snooping but I was curious to know why he has ghosted. If your trolling, don’t bother writing under hear. I’d rather nice comments that will help me. I believe I should move on but I got attached plus, I am moving on but I was just curious.

Forgot to add this in that he demanded that I would be sexually exclusive then he ghosted me the next day when we were supposed to meet up. I messaged him due to telling me that he can’t sleep with anyone - then he ghosted me next day when we were meeting. Plus I respect him being in a relationship and at the time I reached out I wasn’t aware of his relationship status. He’s lovely guy and I just wanted him to know he can’t have double standards (he demanded sexual exclusivity from me and would go mad if he found out if I was going to sleep with another man) throughout this situation, I wanted clarification and peace of mind that’s why I messaged because I thought it was unfair of him to demand sexual exclusivity and up and leave me for another woman. I was unaware of the other woman in this situation. I have talked to him much longer than her. Sorry for not adding this in. Thank y’all for messaging me
