Honestly @buttercup1001 he does NOT love you.
You have deserted your son for this waster.
Your son will now grow up with low self esteem and a whole host of other mental health problems if you continue this relationship.
Your son is more important than how this 'man' (he is not a man, he is scum) makes you feel.
This man has targeted you because you are vulnerable.
I suggest you get some help with why your self confidence and self esteem are so low and then try to rebuild some sort of parental relationship with your son.
Until then your son is better off with his Dad by the sounds of things.
It does not matter how many times you post on here - your 'partner' is abusing you. End of.
You have a choice, leave him and rebuild your life and that of your son's, or stay with him, lose all contact with your son (& ruin his life) and more than likely be murdered by this man.
HE DOES NOT LOVE YOU.
Please, please for the sake of your little boy walk away from this relationship.
