Should I get along with someone new?

A mysterious person in plain view

I have come across a great experience of one-sided love and it has hurt me in many ways. But now, a new chapter is about be opened i.e, someone new is making obvious signs that they like me. It has been for a couple of weeks, and I always would wonder, "should I get along with them and live a happily ever after? Or stick with the only person I had shown my true love and obsession".

They had been following me on instagram and had quite times that they wanted to talk to me about their feelings and make it up to me. But I have been rejecting them as I always isolate myself from them and didn't want them to be hurt. The pain I carry everyday in my life.

But a part me says if I ever love this person what would others think of me, the me that had loved someone else and what would that new person think about how I have been obsessed over someone else. This thoughts had been eating at me... and I am thinking of what's next to come.

What do you think? Do I deserve the love from them or I don't? Should I just have the past on my face and live in isolation.
