DH and I have been together for 10 years and we have 7 yr old daughter together. He has two children from previous marriage, son 27 and daughter 19.
Stepson is independent while stepdaughter is not.
SS finished school 2 years ago and hasn't gone into UNI yet. She is working at her aunts shop whilst waiting to reapply for the 3rd time.
DH is working away and I only see him every second week for 4 days.
Day before his arrival SD comes and she stays for 4 days, which doesn't give us any time alone. She also demands lifts everywhere, shopping trips for just two of them etc and he is happy to oblige.
Whilst he is away she is independent but as soon as he is back she regresses to 13 year old girl.
I am getting fed up of all this and I was hoping that she would get into Uni this year and become more independent. I tried talking to DH about this, he feels that she doesn't see him much so she is missing him "and she is only 19". I resent all this and it feels like our daughter and I come second to SD needs.
I feel lost and not sure what to do any more. I tried gently hinting that she is too dependent on him and it may be time for her to grow up a bit and start looking after herself. His response is that she still needs him and he is there for her.
Am I vbeing unreasonable for feeling so much resentment?
