:) Ok! I hope you don't mind me getting 'psychological' on you. But I want to comment on a couple things you said. I am picking here, but I find that often, there is truth to be found in the words used - because they are heart-sprung.
You said:
I feel it would be best for my daughter to have a two parent family where neither one was a witness because that that is the most loving and stable arrangement and I can't imagine her not growing up without siblings because mine were all only a year apart from each other and it made us best friends, I had always wanted that for my kids.... But things change....
You started off saying "it would be best for my daughter to have a two parent family where neither one was a witness". What this tells me (3rd party view) that what you know to be true is that you must first and foremost fight to ensure that you get your daughter. If having another child with a different man outside of wedlock will be used against you, I suppose you would have to ask yourself, "am I living in alignment with my intention of making sure my daughter is with a two-parent family who are not witnesses?"
You then talked about how YOU can't imagine her growing up without siblings because YOURS were all a year apart and YOU wanted it for your kids. Again, I am really picking on words here (I understand that and am only trying to help you think this through so you get the answer that is most helpful to you). Your daughter doesn't know what it's like to have siblings all 1 year apart. She will not miss it. You do. However, I can read into your statement that because you found it so important (being best friends with your siblings) you want her to have the same positive experience. Understand - she will not be 1 yr apart from her next sibling, but they can still be best friends. Sometimes age distance can make siblings better friends! But, her experience can not and will not mirror yours. Even if they were one year apart - there is a likely chance that they would not be best friends.
So... is this helpful at all? I certainly don't want to muddy the waters. I just like to get people thinking. If this isn't helpful, I will be quiet. (I need to get to bed anyway.) however, if it is helpful, I'm happy to continue the dialogue. IF you want to take this PM, that's fine too.
Much love till tomorrow.
