Well to those that read my first and answered my first question, I was in town today and my sister calls me told tell me that she saw my babysmomma with her ex boyfriend hugging at a festival. She said that they all went as friends and that she had her arm wrapped around his trying to get his attention to look at something. She shouldn't be touching him if she really loves me and with my baby in her. She never even took the time on a weeknight to be with me but the first I see her do it with someone she said she she never had feelings for. She's right but she makes me feel so down. Should I keep trusting her and let her do whatever she wants? What should I do so she can want to spend time with me like that and make things normal again?:(

Ask her why she asks him to go to festivals and not asking you if you want to go.
It doesn't sound right to me that she would just by pass you to ask him (or them) to go.
If they asked her to go then she should have asked to include you too.
I would let her know how left out it makes you feel. Then if she persists in seeing him then start making it more of a thing about why is she seeing so much of him.
