Words unspoken

So this is my first time writing here. I'm not sure how it works buy here it goes..

So some months back I had a breakup with a girl I was deeply in love with. We had been together for more than two years. The relation was beyond perfect because we had a good understanding. I believed she loved me too.

A few months or so before the break up, she started changing. She started becoming distant. Her ways of showing her love changed. I pointed out my concerns and she said should would talk about it but she never really did.

Then one day she decided to end the relation because her heart was not in it any more and she felt we were incompatible. Till today I haven't got closure.

I'm not really sure what I'm asking from this group/app but somehow I hope to get some answers. This problem has caused me to fall into depression and I have had several aniexity attacks over the past months.
