I don’t lnow what to do

I have a 3 year whom I share custody with her father. My days are Sunday thru Thursday and his days are Thursday thru Sunday. He has all his weekends every other weekend and I’ve noticed that on the weekends he doesn’t have all the kids he says my daughter wants to come back with me. He has done this twice. Last weekend he was suppose to have her, he called me that same day telling me she wanted to come with me and I said that was fine.

This weekend he actually has all his kids and today she went over but came back just now. He texted me claiming she’s been asking for me. Yes, my daughter is much closer to me so I somewhat believe it. But tonight I really feel he did it on purpose.

I made a stupid mistake and went over to his house today after we both went to the dmv to get me off a registration for one of the cars. I decided to bring him along to help me since we have been co parenting pretty well. After that we went back to his house and he asked if I wanted to come in for a bit, his other kids where there as well so I agreed. I watched one show and my daughter fell asleep so I said it was the perfect time for me to go since she Wouldn’t allow me to go if she was awake because that’s always the problem or used to be the problem are used to go over a long time ago. We have actually been separated for about four months now and it’s always been such a big castle between both of us he says that he likes to do with my daughter since she was a struggle and if she wants a mother I think the best thing to do is bring her back because she doesn’t want to force her to be somewhere she doesn’t want to but tonight I think he did it on purpose because I didn’t want to stay longer after he asked me to stop and he wanted to ruin any plans he thought I had.

At this point it’s kind of frustrating me that he’s doing this. Then he wants to tell me that my daughter specifically said I told her not to cry and just ask for me when she wants to come. A 3 year old saying this????Sounds stupid. I know her and I know she wouldn’t say of this. I feel like a bad mom If I don’t allow my daughter to come back with me when he claims she wants to but then I feel he easily manipulates me.
