You say we ‘don’t understand’ @Ionlydrinkondaysendinginy, but you’ve been dealt a rough hand in life. No father, no mother, in care, baby at 15/15, MH woes, no family, limited friends, and you’re understandably crying out and desperate for someone to look after you and love you. And you’re blurring the lines between lover and family.
As such, your friend’s father is not the man you should be seeking. Firstly, he’s known you since 11. Secondly, if he’s ‘keen’, having known you since 11, he knows EXACTLY how vulnerable you are, and his pursuing you makes him a very bad person indeed.
You need proper mental health support, to develop your self esteem and self worth. Do you work? Do you support yourself? Can you save money and build a solid and safe home for your daughters, so they don’t have to experience what you did?
That’s where your focus should be. On you and your girls, and having a safe and prosperous life with them. Not trying to seek comfort in the penis of your friend’s father. Please.
We do understand the situation, and we see it for what it is, much clearer than you do.
