Hi, R.. Hon, only you can decide if it is right for you to be with him. That will be determined by the reasons why you two split up. This process is NEVER easy. It really can hurt to share your child with an ex, especially if your relationship is in turmoil...especially if there isn't any peace between you and you two haven't worked out the details of how you are going to raise this child separately.
Yes, there are going to be lingering feelings of love for him, even if you are also hurting very badly. Actually, it is better for you AND your daughter if you DON'T hate this man. Imagine what kind of horrible influence you would be on your little girl if you were boiling over with hatred? Right now you are sad, but that can get better with time.
There are no perfect divorces, just as there are no perfect marriages, but with a lot of cooperation, your child doesn't have to suffer the loss of either parent's love and attention. She's going to be confused; there is no way to avoid that. However, with time and enough patient, loving explanation (without anger or other extreme emotion), she will eventually understand that she has two parents who love her no matter what, even though they choose to live apart.
As for starting over...hey, give yourself some time, woman! Again, consider the reasons why you two separated. Have you two gotten any marriage counseling? Are the problems actually solveable? Or would one person have to swallow his or her entire personality in order to get along with the other partner? In my case, I've been separated from my husband for nearly 7 years. We would've been divorced a long time ago, but we haven't been able to scrape together the money for the filing fee! We were bitter enemies for a couple of years, but lately we have forgiven each other and become friends. I love him dearly, even passionately, but I can't live with his infidelities, and he can't live with my monogamy (I'm a one-man-woman, and I want a one-woman-man). Thus, we can't live together, regardless of how well we get along as friends or how much we love each other deep down inside.
Anyway, give yourself some time. Don't rush into any more decisions. See if you can get some help sorting things out from someone who is OBJECTIVE, who isn't for or against either one of you.
I hope that everything works out for the good of each of you, especially your little girl.
Peace,
Syl
