Hey MemyselfandI, I’m pretty much on the opposite end of your situation. I’m the ex boyfriend, but I’m pretty sure I haven’t used it as a threat against my ex girlfriend with whom I’m still in love with.
I’m really sorry that your ex seems to be threatening you with the thought of his own suicide. I really don’t know how to help get him or you out of the situation thought because I’m still no out myself.
Just make sure that you surround yourself with good friends, and then they will help you stay strong no matter what happens.
I just wanted to let you know that you’re not alone with this problem, and that my ex has the same one, and I’m sure that there are plenty of others.
