Help me check any grammatical errors regarding my sentences, thanks?

I really enjoyed chatting with my ex-boyfriend all of yesterday afternoon. We talked about our love experiences; he has taught me that when I pursue my dream lover not to be too scheming. I also got up the nerve to confess my love for him. We decided to wait for a rainy day next month, when we are together at the bus stop; if one of the first three passengers to get off has a black umbrella, then I will tell him a confession of love. Before then I will try to lose weight in so far as I can, and keep in good shape; He agreed that he wouldn't chase other girls and to be faithful to me. I hope love will enter my world next month.
