I don't know what to do at all?

Here's the story I was with my boyfriend for over a year and one day he just leaves , without calling or anything , there was no fight or anything and i havent heard from him since . Its been about a little over 2 months since he left and since ive heard from him. I tried moving on by going on a date and deleting everything that reminds me about him and to top it off a guy i liked and started dating left me as well without any explanation. I just dont what to do to get over my ex and dealing with everything else.
