Welcome and sorry you need to find yourself here!
Four months may seem like a long time to you but for those of us who are older and have kicked around a bit it is a very short period of time in our minds. That does not diminish what you are feeling....it just should go to demonstrate to you that in the course of a lifetime....it is a very very short amount of time.
I would suggest to you that you look at how you invision your life. I would guess that dealing with all of this stuff probably doesn't even enter the picture. That is ok...you can give yourself permission to walk away after only 4 months. 4 years maybe we could talk about it....but now you need to look forward to building your life and not being held back. This is not enough time with someone to compromise your life style and goals.
Close the door on this softly and respectfully and move on. My advice.....
