bipolar partner deserts relationship

My partner is bipolar, and walked away from the relationship almost two months ago. When we communicate, it is via text message because our communication otherwise leads to conflict. I love this woman dearly and want to work things out, but she is not cooperative. I made the mistake of labeling her with ugly names (verbal abuse once or twice) and even though she says she forgives me, she refuses to come home.  What can I do to start repairing our relationship and gaining her trust again.  I knew very little about bipolar when this happened, but have since started educating myself. I believe she loves me, but is having an affair at this time.  What, if anything, can I do?
