<human>: hey reddit, throwaway because I dont want people that know me reading this.

Basically, 2 weeks ago, my girlfriend broke up with me. She was everything I ever searched for in a woman, she laughed at my jokes, she loved the same food as me, the sex was great and all.
But in the last 6 months we had to euthanize my dog, who was like a little brother to me, I had a pretty stressy situation at work because I am under constant pressure what put me in a pretty quirky situation...

we always seen each other mostly 1 time per week, sometimes 2 times per week. we never really fought that much, we did get along quite well. She always told me she wanted to marry me and have children with me, but in the last 6 months our relationship went downwards. 

the problem? i thought i wouldnt have enough sex with her, i felt rejected when she said to me she didnt want it right now, but at the same time she always said to me how good i looked... i am surrounded by women in my field of work, every day, so the temptation was growing to end the relationship and live my life, i felt i could miss out on something... 

but now i just want to strangle myself for the thoughts i had and i dont know what to do basically.
she always treated me good, and i did as well with her, but sometimes when we met up, i had the feeling that i couldn't wait for her to be gone and be alone again and play videogames or some stupid shit...

i dont really know what to write anymore, because there is so much i would love to say but if you have any questions, just ask...

i have a hard time dealing with the breakup, because i really thought we are gonna end up marrying each other, having kids and stuff, but now my life feels kinda worthless, i kinda feel that i am gonna never find another woman that is like her

how do i deal with this?

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend broke up 2 weeks ago, i dont know how to cope with it, the last 6 months or so didnt went too great, please help
