Hi 
I'm not really sure why I'm writing here but I need to vent and talk to someone so here it is. I've been in a relationship for 2 ½ years with the love of my life, I thought I'd found the person I was going to marry and grow old with so I thought anyway it's starting to feel like it's all for nothing. For the last 4 or 5 months hes changed, he gets mad when I'm with my friends, mad when my two 1year olds are around my friends kid. It makes me feel so lost and so guilty as if I'm doing him wrong. My mental health in return is being badly affected by this. We've had 2 hour arguments about how much this is affecting me and effecting him
He tells me "He trusts me but doesnt trust my friends"
My friends are so important to me, he blames me of cheating on him constantly with them, constantly messages me telling me to *uck off and changes my name on his messages, he wont talk to me for hours or sometimes even days, he says that we should go on a break/broken up and then a hour later acts as if nothings happened. Calls my friends every name under the sun and just generally becomes a horrible person making me watch my back wherever I go, I'm constantly anxious and I am always trying to hide the fact I'm out with my friends because I cant take anymore of this. I love this person so much and hes completely different and so loving if I'm alone orwith him but as soon as I'm with my friends ( going for a walk, soft play, at friends house) he turns into this nightmare, someone I dont know.
I guess I just dont know where to go from here..
