Friends! Always get friends who can help!
I'm in my 3rd relationship right now,
When my girlfriend dumped me I was like "Meh" as I didn't feel for her that way, little saddened but that lasted 5 minutes.
When my ex boyfriend dumped me it was horrid, It was the first time I'd ever felt real love with somebody and when he dumped me I barely slept and just cried 3 days over it, speaking to GOOD friends (not the idiots that say oh, lol) helped me through it. At the time I wanted him back, but now I have found somebody who is better than him in every single way and I never want him back. Things always get better when you find somebody again
Just have to be patient, it was a bit of time and going on dates with different people before I found somebody I felt for.
