He doesn't think he wants to be with me anymore

My world is crashing down, I can't deal with heartbreak anymore. I just want to die. Everyone gets tired of me and it hurts so bad, I dont want to do this anymore. My life has been filled with such heartbreak and struggle and I'm not strong enough for this life anymore. We were going to spend the rest of our life together, planned on getting in a few months, I'm 6 weeks pregnant. My heart hurts so bad. I love him so much. I just can't do this anymore
