I'm in a very similar boat. My boyfriend has huge insecurities. At times, they consume our life to such an extent that he actually tells me to pack my bags and leave. After 5 years.
I really don't believe he's a cheater, but the accusations are hurtful. And they usually start up a whole lot of rage in him. which scares me.

I'm having to take stock of my relationship too. But I know i can't live like this for the rest of my life. I need him to change, and if he wont, then he's not good enough for me
