Someone could correct it?

Hello Tommy,
How are you? Are you having a good summer?
As you know I have been in a relationship with Sandra for four years. with Sandra. Two months ago, I found naked photos (people can be naked, not the photos, photos can be explicit or you can say photos of them naked) and flirtatious text messages between she her and another man and we decided to split up. split out our relationship.

I am feeling very sad, but at least, Sandra doesn’t cheat me (anymore). I relied on her, but she failed (could also be let me down or dissapointed)  another time. We shared many experiences, probably too many, and at the end, our relationship became borring bored (bored you say for persones, for example when you are bored). I was blinded by love. (although it is grammaticly ok, I would maybe say My love was blind)

She has a new partner, she told me that he is an older professor at the university; I think that they are both as different as chalk and cheese. He is retired and he comes from an aristocratic family. At the end she told me that it was a platonic love. What a shame¡¡¡!!! (No these in english :) Love is blind¡¡¡¡

I am obsessed with her. Always she She always comes to my mind, in the morning, durring the lunch time, and all everything (not sure what you wanted to say here) at night, when we went out I go out to walk for a walk with Tesco, my pet. I wish I never met her. How can I get over this situation? I am afraid that it is will be impossible. I will be on a sick leave due to depression. I know, I am a bird-brain, but I am suffering too much. Help me¡¡¡.
Probably if I hadn’t met her I would have been the happiest boy in the world.

Over and out,

Andrew.
