Re: Breaking up
You're welcome. I have to ask --- why did you also post this in the "Divorce Forum"? You're not legally married to him and are at the most, a common law wife.
Why do your parents tolerate his presence? Does he pay rent? Since it's not your house but your parents' house, have them tell him he needs to move out. Give him a deadline and if he hasn't moved by then, they will need to get tough. That may well involve putting his things out in the street.
This whole situation sounds untenable for so many reasons. Not only do you feel trapped in a relationship with him but you are still living in your parents' home. Plus you are attending school. If you are not attending school full-time, look for a part-time job and save up your money.
If your father is so ill that he needs someone with him nearly all day, it shouldn't fall solely on your shoulders to be caring for him. Look into getting some help such as a home health care aide. If you are in the US and your father is over 65, look into Medicare to help with the expenses, if money is a problem.
No wonder you feel like you never had a chance to be yourself. Not only did you get into this relationship at way too young an age but you are expected to care for your father, too. Please start taking steps to resolve both issues!
