consideration

It appears that Peter is more eager to go down the surrogacy route than I am - well he would wouldn't he as he gets a child that is genetically his out of it.

He thinks its better than adoption as a) the child will be his and b) the child is linked genetically to me as it's my sister that's the genetic mother.

I just can't get past the fact that it't my sister and him having children together - that just doesn't feel right to me.

I guess part of that is because I feel so insure about the way Peter feels about me and how he's going to react in this unusual but quite intense situation.

He has said that he has to be in a relationship with someone and care deeply for them in order to be able to do things of great importance - does that mean that his feels are going to be developing and growing deeper and more intimate for my sister if she's going to be carrying his child?
Will he end up falling in love with her as the pregnancy develops?
How will he feel once the baby is born and is handed over - will he be wishing he was with the babies true mother rather than me?
How will I feel about being handed my sisters baby to take home and care for?
Will my sister be constantly looking over my shoulder and criticising our decisions in terms of the way we care for, and raise the child?
How will she behave towards the child - knowing that the child is really hers and not mine - will she try to be a mother to it when we're together?
Will I be over protective and try to keep the child close to me and away from my sister in case she tries to be a mother to her child?
When the child is told and understands what's been said about the way it was brought into the world, will it see my sister as it;s mother and resent me for taking it away from it;s true mother - class me as an impostor?
Will my sister, the child and Peter have a 'special' bond that I will never have with Peter and the child as I was not part of the pregnancy process - just standing on the sidelines waiting for the end result to appear - an outsider looking in?
Will the child hate me for not being its real mother?
Will it accuse me of keeping its daddy and real mummy apart?
Will it love my sister more than me because she gave birth to it?
Will Peter love my sister more than me or instead of me because she gives him children and I don't?

So many questions going round in my head, and so many uncertain feelings about the whole situation,  too many unhappy dreams due to my insecurity about our relationship and all the emotions involved with trying to decide what's the best way of going forward to having our own family.

Emotional overload at the moment and my sister is wanting an answer :(
