Emotional impact upon children/what is right?

Hi all,
I have separated from my husband of 10 years. We have an 8 year old daughter. I am now living in my own flat with our daughter and her Dad has her 2/3 days per week depending on his work cycle. We both work.

Life for my and my daughter just now is possibly in her eyes boring. Its me and her, in our little flat and sometimes she seems to resent it. Will openly say she is bored, her comment is often "I just don't feel myself". Which is quite intelligent I think, as I certainly don't feel myself. In short, I completely get all the bad moments, "mum you are boring" "you are not cool" etc.

Her Father has met and moved in with a single Mother of 3, within the space of 6 weeks out daughter has been introduced to them, moved in on days she is with her Dad and just loves them. All I hear is how lovely daddies girlfriend is, the kids are so much fun, Daddy is amazing. I have no one to play with here mum. She seems to literally count down the days until she goes back there.

Now I am aware she is 8, its a novelty for her and is fun. However, I am also aware that it just feels like the past 8 years of her life has been erased by her Dad and that seems so confusing for her. I am obviously going through the whole, I cannot bare to share my baby with any other female etc. However, when it comes to our daughter, I only ever speak nicely and say that's lovely, comment how much fun she has had etc etc.

However, it is exhausting. I could actually cry sometimes when I am at home with her trying to offer stability, security, a new life for me and her, but also ensure she has all she needs for going back to school and links with all of her family. I know she is only 8. I am just so worried about getting it wrong. I don't want her to pick up that I am upset. I want her just to feel she can come to her Mum and say anything, even if that is I want to be with daddy more.

I suppose my irrational thinking kicks in a lot and when she is with her Dad I just worry I am going to loose her. Every time she comes home shes emotionally all over the place, cries for silly things, doesn't know what to be doing with herself etc. Then by the second day shes her wee self again.

I am exhausted, on high alert and just worried sick about her. I have close family and friends and they are all very supportive and give views around this being a novelty and it wont always be sunshine and roses etc. However, I just wonder if anyone else has experienced this, has things that worked to help their children feel secure and be there for them?

Thanks for taking the time to read this.

Sounds like a hormonal girl trying to be a teenager.
Also maybe the father talking.

There is nothing wrong with boring. Trust me.

Some parents are really exciting, drugs, sex, violence, no homework, no school, no friends, cleaning, not allowed out, etc at an extreme.

It seems she has a great time at her father's. Everything is new. Wait a while.

I would try to do thinks that she cannot do at her dads with kids around. Even though looking after kids is really what most girls want to do.

There are some things you can do with kids her age. Makeovers, sleepovers, movie night,

Don't compete, with something you can't provide. See the difference and embrace it. Caution it might involve spending some money and it might not. Just being thoughtful about including her when she around and doing boring things (homework) and some exciting things (us time).

Good luck.
