What if she forgets me?

A no contact period will definitely show her that you are NOT there to waste your time waiting around for her. Show her that you’re strong and that YOU can move on too!
Don’t read her messages, show her that you’ve dropped all of your attention. Disappear for a little while and see if she comes searching for you.
I would strongly recommend not messaging her anymore and leave her wondering. Make her realize that you’re gone and rather SHE is loosing YOU, not the other way around.

Thats ok. I can relate to how you feel. I am going through some struggles of my own right now. It’s difficult isn’t it, not talking to them and basically erasing them from your mind slowly (temporarily). Just think about it this way, would you want to be in a relationship were she has absolute control and she’ll just keep playing around with your feelings and jump back and forth between you and her best friend? You tell me, does that sound comfortable and healthy?
You deserve better, i don’t know you but everyone deserves better than that. If you really want to give it a second shot with her, you need to let things cool off for a while. Re-compose yourself, make yourself a new version of you. Pick up some forgotten hobbies you always wanted to do, stay active! Make yourself attractive to her.
For example, in my situation; i haven’t talked to my ex for 3 weeks now. Yes i miss her and yes i still think about her. But i’ve accepted that i can’t live my life being all sad with myself. I know that once i am happy with myself, everything around me will lighten up slowly or fast, the possibilities are endless. AND I HAVE PROOF!! I got a great new job a week following the break up, i got offered a second job, i am top of my public speaking class, i’ve had time to go to the gym 4-5 times a week, i regained my six pack and i can bench press again!, i’ve picked up the guitar more often now and i’ve self taught myself songs i always wanted to learn. Although i don’t have many people i hang out with, i never give in to loneliness and i keep myself active. Now it’s week 3 after the break up and i’ve recently found out that she has asked about me!
That is my proof, things fall together eventually. If you genuinely want things to work, all you need is patience and a bit of courage to push yourself to find yourself again! Find that confidence and when the time comes, show her. Show her that amazing person that you truly are, show her that you’re happy and you’re doing great.
Contacting wise, give it a month or longer, it all depends on your situation.
For example, its week 3 now for me and her and i have finals in 2 weeks. I am going to wait until all exams are over to reach out to her. Why then? because i want to avoid any sort of stress factor that may intervene with me contacting her.
It all depends my friend, keep us posted and keep your head up

I have mid exams too on dec 8th. He even didn’t try to contact me. I am in day 17 now..it’s tough. With all ups and downs. He might forget me either. He might move on. I don’t know. I cut all the contacts and soc-meds. I hope we’ll pass the exams. Gotta focus. Stay strong!!
