Moments like these'

I often find myself frustrated over things I have no control over or perhaps I do in a way. Only thing is I would need to make a lot of very stressful decisions in order to have any control over this situation whatsoever. I unfortunately feel really torn on what exactly to do. I have waisted half of my life pleasing other people. Ive always tried to do what would help my kids have what they need what they want and then some. in return sometimes it made me suffer a great deal in the end. At one point in my live doing just what I thought would keep them happy meant staying in a horrible situation physically, mentally and emotionally. Unfortunately, I stayed and paid the price for doing so time and time again. This point and time it's not physical and only one child in the situation with me. Yet, I still feel like this is the hardest decision out of any of the situations I've ever been in. I may not want to face the fact of truth in this whole situation. I go between am I being a childish big baby or am I being a traumatized individual who tends to live in their past unable to move forward and make healthy choices. My15 yr old daughter is the only child left at home. I want her to have an amazing three years left at home with her mama who loves her more then I feel I'm able to show at times. Due to being mom and dad all the time because her biological father is never in her life for more than two weekend a month every 6 month of the yr. I hate him coming and going yet if I say nope, you are not seeing him then I feel I'm hurting her feeling. I don't want to hurt either her or her father I want to set boundaries make him fallow through with his promise to her. The one he is hurting is our daughter not me because I love her and would never let her leave home if it wasn't the right thing to do. Co-parenting healthy co-parenting that is what it's about right? She deserves so much more than what she has been handed I feel like such a failure at this point. Anyway, time goes by fast three years is not a long time but three years alone with my daughter could mean the world of difference at this point with her. I hate the thought of leaving my hubby, yet a part of me feels maybe a few years living apart could make us realize when or why not we should make it work. We will either grow from the choice to be living apart and healing ourselves or it could make us decide we are better off apart. UGH, my stomach aches and I feel like throwing up at the thought of not being together in the end. I need some healing with my child. please help me give me some advice or feed back! I need you to helpme decide.
