<human>: Can you succinctly summarize the text in 1-3 sentences?

Hi there.

Today, I'm doing something that I really want to do since a really long time, I need to talk a bit.
I was in a relationship (my 1st real love) for 3 years. Last year, we broke up, because we were arguing more & more.
2 year later, we see each-other sometimes. That's a bit recent.
And this is how it goes : we chat, we see ourselves at home, we end cuddling or sometimes kissing. But everytime it happens, the next day is like nothing happened : then no contacts for a long long time, and we restart. Again, and again.

I decided to stop sending the 1st text message. But she does send that message. And we talk a bit. But we run really fast out of discussion. And I'm always searching for a subject to talk to her. And everytime, I really feel like shit. Because she doesn't restart the conversation, I feel obliged to do it. I definitely shouldn't. I know. And it makes me really feel like I'm stupid.

I don't really know what to think of this. I mean, I think I'm still in love with her - I dated some other girls, but, somewhere, she wasn't that far from my mind. 
I don't really know her position. I want to talk to her about this but I don't know how to proceed. I'm really stuck, and this is getting on my overall mood. 
I feel sad, I feel down everytime I think of her. 

I mean, I know that it's been 2 years. She didn't dated someone else, we both kept Facebook photos of us when we were in love in our folders.
I'm really lost, and I think this is the right time to ask some help, some advice.

(As you may have guessed, I'm not an English native speaker, so sorry for the language mistakes.)
<bot>: 1st real love, 3 year relationship, still not getting over 2 year later, starting to make me really sad.
