I never imagine these things

My mom used to say, "You always try to do all the new things for the first time. Meanwhile, you don't hurt or damage something or someone." But sometimes it is impossible even though you try to do your best in special on relationships. Today I needed to convert in a psico person*** actually in psico girlfriend. and I hope to take do this behaviour only one time once in my life but it was necessary because he doesn't understand. I just wished to hear from him I love you "I love you" from him, and I'm sorry but he didn't, so he leave left me.

**I'm not sure what this means exactly (no estoy completamente seguro que significa este) Maybe:

I needed to go psycho on my boyfriend. OR I became a psycho girlfriend.

"Psycho" = una persona loca

Another version (my interpretation):

My mom used to say, "You always try to do new things for the first time. Meanwhile, you try not to damage or hurt anything or anyone. But sometimes it is impossible, even though you try your best in romantic relationships. Today I had to become a psycho girlfriend, and I hope it's the only time I have to do that. It was necessary because he doesn't understand me. I just wanted to hear him say "I love you," and, I'm sorry, but he didn't, and he left me.

Sad story! :(
