Mommy is always gonna take her little boy’s side over yours. Plain and simple. Apologizing (if YOU’VE done nothing wrong)only serves to justify his actions and to make you feel like you’re the reason he acts this way. Then the “If only I could ..insert action here…then he would change” thoughts start to come and it’s downhill from there. Life is short and, while you may be young now, you shouldn’t waste anymore of it in this toxic and harmful situation. Just my opinion, of course, but, from having experienced this type of relationship before, unless he decides to change and get help for his issues it’s unlikely things will change for the better. They can always get worse though.
