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

So this morning I (22M) matched with my ex (20F) on tinder. It really had me rattled because I only liked her profile thinking that she would have not liked mine since she was the one to initiate the break up.  

Once i liked her profile, i got that message screen saying how it is a match; my heart sank. I was hoping that i could try an keep moving on and bettering myself but then i get this little reminder. Was this a sign? Does she want me back? Should I send her a message? Just keep her as a match and keep moving forward? I don't know what to do and now I have all these thoughts swirling in my head.

Our breakup was a real surprise to me and not at all my choice. She was going through some things and we hit our first rough patch throughout our 3+ year relationship. I felt as though she was just tired of having a boyfriend and just quit on our relationship. As soon as we broke up, I started the no contact and have only seen her once in the last 3 months.

So now i am sitting on my deck with a cup of coffee wondering what i should do. I want to just move on but can't tell if this is a sign. Please give me some advice because i resented this woman for giving up on us and now this little situation has my mind racing. I know this girl and me are not good for each other but a small thought in my mind is telling me that it's meant to happen.
