No, to me its not normal.
Please listen to the advice above. You are not helpless and if you want things to change, then they will change, but you got to take different steps (nothing changes if nothing changes)
Also might I gently suggest for you to get checked for STDs/HIV? I just read someone's post about a lady getting HIV thanks to her partner's adventures.
You inahaze are a great woman who has gone through a lot already, imagine if you lost your physical health? and for what? please take care of yourself. I, dear inahaze, have the feeling you are playing with fire.
