Apologies in advance if this turns out very rambling but I'm in a state and need some opinions.
So, I met DP last year, we're moving in together in a new area next month. I have DD (9) who has no relationship whatsoever with her biological father (he wanted nothing to do with her). DD and I are extremely close, I've not really had any significant relationships since I had her (aged 19) and so it's mostly been just the two of us.
Now, DP has a son, aged 7, who he has joint custody of with his ex. His son is autistic. He has the most acrimonious relationship with his ex - they had a two year custody battle, she levelled a slew of false allegations about him to the Police, Social Services became involved...it's been a nightmare.
So, until now, I haven't spent long periods of time with his son. As we're building up to all moving into the new house, his son is staying here for weekends. And I'm struggling. I don't know how to deal with his behaviour when he screams, throws things, hits DD, talks complete gibberish and spends large amounts of time staring into space or being totally hyperactive. Sometimes, when we're outside and he's calm, then we can have nice conversations (always slightly odd but nice) about gravity, aeroplanes, science etc. But these are few and far between.
I feel totally torn. I want to protect DD. She's finding him difficult to deal with as well as adapting to DP being around all the time. I feel so guilty that I'm uprooting DD from her friends and school to move to a new area so that DP's son can stay at the same school and be near his mother. I'm filled with dread that I'm going to have to deal with DP's son for a week at a time, every other week. I can't cope with him waking up at 5am and shrieking. I don't want him to wake DD up. I just don't know how to cope and how to deal with him. Especially since he's been through so much crap with his parents, is so vulnerable and I have no experience at all of dealing with Special Needs.
I want DD to have a proper family, to have as close to a father as is possible and to have siblings. I love DP and want to be with him. But how on earth do I deal with the situation? I'm sitting here surrounded by boxes, sobbing that I'm leaving this area and moving to a whole new place.
I can't talk to DP about this - what on earth could I say? That I can't deal with his Special Needs son? That I wish I we only had him at weekends and then I could at least recharge during the week? That I'm grateful that I'll be starting a job with very long hours in September and thus won't have to be at home very much anyway?
I feel like I'm such an awful person.
