Girl's Behavior

Is she having sex with someone else, she put me on dnd and won't answer my calls or texts, should I fall back or move on, she says I'm not blocked?

Long story short, I met this girl and the father of her children lives with her. They split bills and she has three kids that lives with them too. I noticed funny vibes everytime he would see me or know I'm around. Like I would hear footsteps creeping while I'm trying to have sex with her. Weird shit. The thing is, we hit it off well and we stopped having sex and she stopped texting me and talking to me really because I got locked up for a little over a month and the guards in there didn't let get her phone number out my phone to call her so I haven't spoken to her in a month so she was probably mad I haven't spoken to her.. I got out early this November and I went over to her place and she changed, she started acting distant. And it seemed like the father of children was controlling her and locking shit down or something I don't know. But she kinda spazzed out on me and was saying I was forcing her to have sex when I thought we was feeling each other because before I got locked up we literally had sex a couple days before I went to jail and the vibes was good. She has since told me that she lost her job and benefits and she's been arguing with her dude as I like to tell her.. But the thing is, she would diss him to me about his sex was wack and all this shit and she couldn't keep her hands off me and now it's been 3 weeks and she's been dodging me and told me that we're just friends and stuff and it wasn't that deep and that she isn't relationship material which I told her she was.. It just seems like she fuckin other dudes or someone else and she assured me that she isn't but I don't know. Long story short, I've been texting her a lot more than usual and I think she's gotten annoyed and I was right because she ended up putting me on dnd and telling me she put everyone on it when I called her from another number and she picked up.

And I also noticed she'll pick up random numbers quick like she talks to a lot of dudes. I don't know I think she's a hoe and she's probably putting me on dnd so I don't interrupt her time with whoever..

Most girls ain't going a month without sex so I doubt I'm the last person she had sex with.. What do you guys think? I feel really sad and heartbroken because I really liked this girl. She texted me and said I'm on dnd and she sees when she gets texts and calls.
