<human>: Can you summarize the given text in a few sentences?

So I met this girl early in the year and we instantly connected. We talked for months and gradually became a couple. One day we kind of just said 'we are boyfriend a girlfriend aren't we?' It was amazing. Everything just fell into place and felt like this could really work. 

She was my best friend that became someone I truly had strong feelings before. I had been in an almost 3 year relationship in the past and everything about this new relationship was so better. Feelings stronger and generally I enjoyed her company. 

So then fast forward to last night. She got in a big fight with her mom. Her mom took her phone and read through our texts. There were some texts that had me talking about my issues with depression and past drug addiction and how I get cravings etc. Well her mom didn't enjoy this. 

She has been forbidden to speak to me at all due to the fact that I'm older and my past and some current issues with anxiety and depression. 

In this situation I showed respect to her mom and told the girl that we have to stop talking, it was a rough phone call we had and it hurt us both to say goodbye. This was the best relationship I could imagine. Best friends that turned into more. 

I'm mainly just looking to get advice on how exactly I can get over something that wasn't finished. It's always going to make me wonder 'what would have happened?' Yeah i'm only 19 so I should 'get over it' but it really doesn't seem like it'll be that easy. Maybe someone has had the same experience as me and can give me some insight onto where to go from here. Thanks for reading this long story!
