Partner spending weekend fitting ex wifes bathroom

[user1467973151]

If your partner was fitting a bathroom for his ex wife for 4 months spending a large part of every weekend doing this, what would ypu think?
For reference they have been divorced years,definitly just a friendship, adult daughter (28) lives there also.
Been together 4 months, bathroom was started before we met.
We are very serious about eachother and very happy with him.
But this is upsetting me now.
Spending all day sunday and sunday evening there until around 8pm.
Meaning Saturday is his only day off. He is constantly tired because he works really hard then this on top. Which means hes often tired and not willing to do things saturday evenings with me due to being up early to do this room.
We went for a meal Saturday night but was asleep by 10pm and up at 7 ready to do the room. So i feel its impacting the whole weekend. He also spent easter sunday and bank holuiday monday there while i was alone.
Am i right to feel annoyed?

It takes 5 days to fit a bathroom…

I really don’t see the problem. He started it before you met him I also met the mother of my husbands daughter after they had split up years ago. Amicably. She and I get on really well and she will always be part of our lives as she is the mother of his daughter. Makes life easy for everyone. Ofcourse it can be a different story on other situations but I commend him trying to help them out.

If he had spent most weekends there for the past 4 months, you would seriously be happy?!

My daughter, in social housing, had her bathroom and kitchen stripped back to the brickwork (I saw it) and a new kitchen and bathroom was finished in five working days, I call shenanigans.
