This may be a long post so I apologise...
I think I want to leave my wife. There I've said it. Been together for 11 years (I'm 34) and have a daughter who is 5. When my wife & I met we were both massively overweight and going through weight loss surgery. Things weren't awful back then. We had weight loss in common and it worked well. After the birth of our daughter, things took a spiral. We were both losing large amounts of weight. I was doing this for my health & to be able to experience new things in life. I have a very good job, earning well & was generally happy as I've always craved that family life and being able to provide.
My wife started going on social media and gaining a decent following related to her weight loss. Over the past 4 years I feel she has just got lost into this world. For years I have asked for help with the general housework and tidying, but to no avail. She will help out the first week after saying I need support but then falls back into her old ways. She's also never home. Most evenings are spent at the gym or exercises classes, or going out with her new 'insta' friends. I want her to be happy and experience life, but I feel that she wants to go out and show off and never asks to do anything with me. I have felt like a doormat and just her convenient 'childcare'. My daughter is the best thing that has happened to me and this is what is making the decision so hard. Most weekends are now just my & daughter and I anyway but I worry what will happen if we were to split as I work shift work and my hours can be all over the place.
The past 6 months have been especially hard...I have got to quite a low place and currently on a low dose of anti-depressants. I spoke to my wife about this recently and how I want to make this work, spend more time together, but I desperately need more support around the house (for the record I do absolutely everything) despite working full time and her part time. She said she was understanding, however that same weekend she made plans to go and see friends and once again it was my daughter & I at home all day. There has also been some suspicious behaviour recently, new codes on her phone, always up late at night messaging (she says this is all weight-loss) and just generally being cagey about where she is off to. I have never suspected her of cheating, and deep down I don't think she is, but I do know she loves the attention which she is getting loads of now as she looks great. I always tell her how attractive she is to me and make her feel special. In the past I've planned trips abroad for her birthdays and trips to nice restaurants.
3 years ago I actually out right asked her if she wanted to be in this marriage anymore as I could feel she was massively disconnected. She said she did and loved me and didn't want to leave. I wonder though if it's just her loving the life I provide her rather than loving me.
I feel now I'm at a point where I feel exacerbated and it's with sadness I say it, but I'm no longer in love with her. I have no idea if we can come back from this. I have no idea how to even start the process of leaving, but I have a feeling it will be like a weight has been lifted off my shoulders...any advice?
