I thought this was never going to be me....

I've dated a few guys and I have cut it short all times while the guys begged and cried for me not to leave and today it was my turn....I've been in a relationship for 3 years we have 1 son together and he has raised my other 4 kids hes been their father figure this entire 3 yrs even thought they dont call him dad they acknowledge him as their step father me and him had a fall out hes been at his mom since Monday and today he came to see the kids and afterwards I asked can we talked he said he loves me but he just cant keep doing this it broke me it shattered me I probably begged him to come back home and not leave me about 50 times I know what a dumbass but honestly i grew up in the foster care system i never knew what a real family feels like I never had no affection shown towards me and he is my family with our kids and hearing him say those words crushed me to pieces if that means me having to work on myself to get our family back that's what I will do I never thought I would be begging a man to stay but we have been thru so much I dont want to try and start over with anybody else 😭😭😭😭😭💔 I don't want to invest energy into some body else
