Can a native speaker of English check structure and grammar of the sentences, thanks?

I really enjoyed chatting with my ex-boyfriend whom I favorite whole afternoon yesterday. We talked about our own love experiences of foregone times; he has taught me when I pursues my dreaming lover don't too more deliberately, I also got up the nerve to confess My love for him. We appointed rainy day we will together stand in the bus stop next month, if first three passengers get off and any of them have a black umbrella, so I will tell him a confession of love; before this I will try to lose weight in so far as I can, and staying in nice shape; He grant my wish which is neither will not accept other girls except me lusting after him, nor chase anyone. I hope love will come into my world in next month.
