Struggling

I'm really considering leave my partner. I'm unhappy in myself and us together. We've been through alot and I've all stuck by him through his own struggles but I just can't cope any more. I feel I don't get the help and understanding from him. I see that he manipulates me using his and my own feelings and actions against me It's really taking a toll on my own metal health. We have nearly 3 year together and own our own house but I need out. I really don't wanna leave the family home but I know I'll be the one who will have to leave as he say he choice to break up and leave. I'm scared of what's to come as I've tried to leave before but he always say certain things and worms his way back in. Don't know the point of this post, just a places to vent and let out my true feelings as I don't really have anyone to chat to about anything.
