Confused and need advice help

So on May 12th I started talking to this guy on Bumble. He's 23 with 2 kids, which I didnt see till later lol But it didnt bother me. Then we started talking on snapchat. We talked for about a week plus a couple days. We had plans to meet and go to the movies on a Tuesday, and he said that later that weekend he'd like to take me out on a date. Ny first ever date. Lol I'm 21 and never been on a date. Monday, day before we were supposed to meet for the movies, he says he can't because he was just told that he had to work a double shift. So of course I understood and I said that hopefully we can still go on the date later that weekend. He said yes for sure he was gonna be available. He apologised and said he was really looking forward to seeing me Tuesday. Then he ghosts me that week and the weeks to follow. I decided that, you know, a couple weeks have gone by and I feel like I need answers. So I looked for him on Facebook and messaged him. In my message I basically apologised and that this wasn't like me and I didn't mean to look for him on Facebook but I really needed answers cuz I was left feeling confused and wondering what happened. I didn't want to make it seem like I was accusing him of ghosting me cuz he never seemed like that kind of person to me. And there could have been other reasons that happened. So I just said something like "If you really did ghost me because you weren't interested, you should have just told me and i would have understood." Yesterday, June 11th, he finally got back to me. He said "Hey, can I get your number so I can call you and explain everything? I don't have snap anymore" So I did and he calls me. He says that he was at the beach with his daughter that week and this massive wave was gonna sweep her off her feet so when he went to move her, his phone got damaged. He is currently using a flip phone. I didn't get to ask how he was able to use Facebook though. He said that he hadn't used Facebook in a while and he had to reset his password and he just saw my message. He apologised and said he never meant to ghost me that that's not the person he is and he would never do that to someone. We started talking about other things and just catching up. He then said something like, "You've probably seen my Facebook and gone through it" I said I hadn't really. I just found him and messaged him. Now I may have snooped a little but he didn't need to know that😂 He says ,"Oh ok well if you do see pictures of another girl or me and this other girl, just know that she's my ex girlfriend." Now, I had seen those pics they were pics of them and their two kids. But I also remember seeing his status and it said single. Now today June 12th I decided to go through his profile, because I'm curious and wanna know more about him. His status says in a relationship since May 10th, 2019..... I clicked on the girls profile and there's a photo of them together they took yesterday.... So what the hell.... I got to talk to him enough to like him and now I'm feeling kinda crushed. I texted him but he hasn't answered all day so I messaged him about it on messenger and he's offline so idk when he'll see it. I'm just so confused.... How was it that it said single a week or two before and now it doesn't. The thing is we weren't friends on Facebook so maybe he chose only his friends to see it. Then he messaged me back on messenger and his profile doesn't give me the option to add him as a friend. So I though ,okay are we friends now. But I looked down my friends list and he's not there. Idk how it works, I'm rarely on Facebook and I hardly use it. I just need advice. Idk what to do. I'm feeling so confused and shitty
