Ex advice? (Kinda long) im sorry but im pretty down about it

Me and my ex had been close friends for years before we decided to start a friends with benefits thing and two weeks into that we decided a relationship was the right thing for us.

It was a great relationship, i can't pick out very many bad things about it. Through the whole 6 months we were together. Towards the end (which was just a few days ago) we had been fighting a lot over small things and we decided it was best if i left. Although we domt love eachother any less than we did, and we still feel we are soulmates. He asked if we could still be friends and i said yes.

Well he said he missed me yesterday and i had been thinking and realized that i was the one that caused all the problems because of my insecurities and depression. I let it get in the way of a lot.

So I asked him if we could try again if i took some time to work on myself. And the picture is the rest of that conversation. He is the grey and i am the yellow messages.

My question is: should I just be patient and work on my problems and see what happens or do you think the odds are too low and i should work on myself and just try and move on?
