I feel horrible just writing that 
My ds has a 'best friend' in nursery. Before Christmas bf's mum gave me her number to arrange a play date over the holidays. We met at soft play and tbh it was pretty strained, the dc played happily together but we didn't really click. She didn't stay long and that was that until a few weeks ago, she invited us to her house to play. I felt on the spot a little bit as she asked in front of the dc and they were pleading so we went.
Again, we didn't have much to talk about but passed the time playing with dc. As we left, dp's said can they come to our house next time and I said yes. (Felt rude not returning the favour)
So this week they came to us, and stayed all day. I was literally cooking dinner with her watching me in the kitchen before they left. My house was trashed and I was shattered. Now I would like to leave it at that, politely decline any further meetings but I feel guilty. She texts me everyday. Says she has no other friends in the area and she's so glad she met me.
I feel awful but honestly we have nothing in common and it feels really awkward. Aibu? WWyd?
