Every bloody weekend my dad asks if I can have my sister

[MummytoLeoX]

AIBU? I'm 39 weeks pregnant now 40 on Monday and I'm EXHAUSTED! My half sister texts me every weekend saying "dad says are you doing anything today because he's going out and I can't go" BEARING IN MIND she has a mother she could stay at her house. My dad has her every weekend but ends up going out in the evening! I had her stay last weekend and she annoys me I can't cope she plays videos on her phone while I'm sleeping asks if we can order a takeaway or if we can get some sweets and food from the shop and watch a film. I took her to cinema last week Saturday and had a KFC then the next day we had a pizza my dad didn't collect her until 9PM on Sunday. My dad didn't even give her a penny to bring so I paid for everything I'm not rich! I'm only on maternity allowance. Not to mention the mess she leaves in my bedroom constantly on her phone face timing her friends.
If I say to my dad oh I'm abit tired this weekend or something he will take it as I'm being stuck up and don't want to see my sister.
What can I say? I haven't replied to her text yet she's 13.

your dad is sounding choicer and choicer...

Oh he will grumpy old blonde! He can't seem to stay in one commited relationship either. Constantly cheating on his long time partners awful awful man. I could go on

she's 13 so should be able to entertain herself at home for a couple of hours.

You are not a stuck up bitch. You are a grown-up adult who has a family and commitments of her own.

If your Dad was able to relate to you as a fellow adult he would be able to realise this and not take you for granted - he could figure out that you probably have plans etc and aren't there at a moments notice when he clicks his fingers. You are his daughter but you aren't his child anymore - you are an adult.

Let him have his sulk. It's his problem. And work on your relationship with your sister independent of him.

Clearly your DF is not invested in his child.
That is not your problem and this piss-take cannot continue.
She is his responsibility not yours.
Be firm - you'll be busy enough once the baby arrives.

She is old enough to be at home on her own OP,this is not your problem your Father is the problem and he needs to grow up and start acting his age!

If he wants to grow old and end up alone with no kind of relationship with any of his children because of the way he behaves that will be his problem not yours or anyone elses!

Tell him no more,you will decide when you want to spend time with your little sister not him!You are a grown up and your about to become a parent yourself would he think it acceptable if you told him when he'd be expected to look after your child?! I bet not!

If your worried about your Sister I'd speak to her Mum and let her know what's going on,if it was my DD I'd want to know if her Father was being an arse and dumping her at every given opportunity rather than being a good parent and looking after her.

I'm surprised he even had the cheek to get my sister to text me to be honest. He doesn't even bother to call me to see how I'm doing hasn't even brought anything for the baby. I feel so much better now after saying NO today as I normally just suck it up but you ladies are right it's his child not mine. I've texted my sister telling her I love her and il see her soon. I have her all the time and take her out for meals and shopping and things so I shouldn't feel bad.

Take charge. You decide when you want to see your sister and plan it. That way the plan is shared, everyone knows what to expect and when and at least that way your sister will have some quality time with you, when it suits you and doing what you can manage and choose. Sounds like your sister needs some special time with you given her back story.

If you set out your plans, for an afternoon visit; something like 'why don't you come over at 1.00 on Saturday and we can watch/do our nails/sort out the babies nursery/ or whatever you both might like to do together...and then before you leave at 7.00 we can bath the baby, cook a meal together and eat before you go home'. This gives her an expectation, it provides something you have chosen, gives her some quality time and some probably much needed life skills, whilst letting you be in control and prepared .....and if she doesn't like the sound of this she won't come! But that would be her choice. Something like that could be set as a pattern; every other Saturday we will .... together.

Almost certainly assumed that it would be harder for you to say no to your sister directly.
