I'm a single mum and I work full time, Monday to Friday. My mum lives about 30 mins drive away but works on Saturdays, so I always 'hold' Sundays for her so that she can see her only grandchild. It's never been put in stone but it is understood that either she'll drive to us or we'll come out to hers (normally she comes here or we meet elsewhere as it's a 2 hour bus journey for me to get to her, so 4 hours travelling with a toddler, not fun).
With only Saturday and Sunday to do everything needed outside of work - spending some actual time with my son (not just breakfast, bus to nursery, collect from nursery, dinner time and bedtime), cleaning, food shopping, seeing friends, anything else that crops up... The weekends get pretty intense, although equally lonely.
When I called her this morning she asked me what the plans were today and I said that it might be nice to take DS swimming. He loves swimming and she has only seen him swim once when he was very little and hasn't been in with him. She said that she would only want to go swimming if it meant she could do her 40 lengths or so, and that she couldn't do that if she was going swimming with me and DS, so no.
I feel pretty hurt as IMO the point of her seeing DS on Sundays was to spend time with him and have a relationship with him. I thought that she would want to go swimming with him.
On the other side, perhaps she just doesn't want to go swimming. But it feels much more like she doesn't want to go because it would mean playing with DS rather than doing something for herself.
Bearing in mind that this is the same mother than told us one Christmas that the only reason anyone has children is so that you have someone to look after you when you're old...
I'm not sure if I'm overreacting because of PMS or if I'm justified to feel let down by her. AIBU?
