Just looking for some advice really. I know there's no fix. It might just be cathartic writing it down.
I've posted on here about my mum lots of times. She was vile to me when I was growing up and if I didn't keep her at arm's length she'd be vile to me now. That's ok, I've come to terms with that.
What I thought I did have was a great dad. (They are divorced)
Last week I finally realised I do not 
So, having not done any kind of 'family holiday' type thing since I was young (my mum does a centre parcs thing with my (adult) brothers every year but I don't go) and since I've got a month off before my new job starts, I thought it'd be nice to accept my dad and step mum's invitation to stay a few days with them at a big house they'd rented in the lakes. My younger brothers would be there, plus my SIL and baby nephew. DP was up for it too. They'd already been there for a few days when we arrived.
Dad was supposed to pick us up from the station (nearest one 15miles away) didn't 'tie in' with his day particularly well apparently so he got my brother and SIL to do it on the way back from taking the baby swimming. Baby hates car seat. Screamed all the way back, nothing to be done as had to be in car seat obviously, stressing my brother out who was driving so he missed about three turnings and got lost. So nerves were a bit frayed when we arrived.
Evening went ok, dad barely said two words to us, we watched some TV, dad inexplicably starts being loudly homophobic towards some gay characters on a program. I challenged him. (I was really embarrassed and DP was like 
) He says he's paid £££ for the house and I am ungrateful and how dare I challenge his opinions. He stormed off to bed.
Everything was centred around 'his boys' (my brothers) they are like princes to him. They went out on 'lads runs', a fishing trip/picnic in the boat, played endless games of pool. It was a obvious he didn't want to spend any time doing anything with me. If I tried to 'join in' I was made fun of and laughed at by all three. I felt like I was spoiling their fun so I gave up.
DP said to be a couple of times he was quite shocked about how my dad (and my brothers) was treating me. Usually I won't hear a bad word said against my dad but I was starting to get really down about the whole thing.
On the last day, our train wasn't until 2pm as it was a cheaper one. Plan was for dad to drop us at the town at 11 after they'd packed up the holiday home and we would just find a country pub to have lunch and read our books until the train. Dad decided due to car space and luggage he couldn't do that and also this town was out of the way for him and not on his route home, so he dropped us at 9:30am in a town a bit closer for him so he could get back and load up the car. We had ages to hang around and had to take a bus to where we needed to be, that's annoying but not terrible. What really upset me is that I learned that after they'd all packed up the house, they had a family brunch in the same town they'd dropped us in and didn't tell us. I saw the photo on Facebook. I asked him and he says 'well I assumed you'd have already had breakfast.'
I've been really upset since I got back. Now I think about it it's always been like this and I feel like the black sheep but my mum was was horrible my dad looked like a knight in shining armour in comparison. And he's not
