AITAH in this situation.

[LoveBug190011]

So I just wanted to get an opinion if I’m the a$$ in this situation. 
 

So for context I’m in a relationship with a guy who has a child from a previous marriage. I try to coparent the best I can but mom isn’t a huge fan of me but that’s a whole other thing. So I’m doing my own thing when I get a message from mom asking if I’m available Saturday. At first I said I wasn’t because I had made plans this past Sunday. Decided I could push back those plans and take her. At this point my partner is also messaging me because I told him I wasn’t able to but because I felt like I was getting passive aggressive vibes I decided to just push back my plans and watch her. Well from the sound of it it made it seem like I was just watching her Saturday morning. Partner tells me she’s staying over Friday night and into Saturday until mom picks her up. At this point I’m getting frustrated because I have no idea what is happening. Getting told what seems like 2 different things. So call mom and she doesn’t answer me. Sent my partner a screenshot shot of what mom had told me and got left on read. So am I the @$$ for being slightly ticked about this whole situation.

Your post is a bit confusing. Some questions:

Take who? The daughter? If I understand, Mom was asking you to babysit?

Wasn't able to do what? Watch his daughter?

Do you live with your partner? Where was Dad going to be that he wasn't available to be with his daughter? 

Why was the girl's mom messaging you to begin with? I am confused why your partner wouldn't have the been the one to ask if you could watch the daughter. How long have you been together?

Triangles never work. It's up to partner to make arrangements for his child. If he wants to consult you about any given times, then that should come through him. Deal only with him.

No. You are getting mixed messages. That is frustrating and annoying. You have ever right to be upset. 

Doesn't mean they are the problem either or you should be critical of them. No one is a villian, it's an issue of poor communication,

If any of you are making any plans, be clear from the start. Ask specifically what the timeframe is so that you can be prepared. Insist that if someone needs to change plans, they let everyone know as soon as possible. Be clear and specific about all plans and times to avoid this confusion in the future.

Yeah 

Never fun to be in the middle 

How often does this happen ?
