Thanks guys for reading this

hopefully you can help me.
I've been with my girlfriend for a year now, things were great in the beginning, but lately it was starting to become boring.. We see eachother twice a week and once in the week we have sex. I think she is becoming less attracted to me.
Lately we barely talk to eachother and if we talk, it is really boring talk, how her day was and mine etc... If we see eachother we still have great fun conversations, but, she barely shows affections, no hugs no kisses.
So, I was kinda sick of it and wanted to end it, but I'm still really in love with her, so I decided to take a break of 2 weeks, no contact! Is this a good decision? She said she was going to miss me and she started to cry..
What is your opinion? Can a break help? I should not initiate contact right? And what if she does? I really miss her now, fuck.
