what should i do?

I having difficulties understanding your question.
You stated that you had feelings for this male friend and that he turned you down. You also stated that you stopped talking to him due to some misunderstanding. What was the misunderstanding that cause you to stop talking to him?

This male friend had created misunderstandings between me and my best friend about 3 years back
From that time, I choose to ignore him but he constantly messaging me
Finally, I forgave him
& I spoke to him
Now we both are in different cities
and when we share our kiss, he lied to me that that was his first kiss
After some time, he told me that he lied to me
Again we met and spent some quality time
But after that, I felt neglected
What should I do?

Try calling him. Talk to him. Tell him that you haven't spoke to each other in a long time. Tell him that you were thinking about him and that you wanted to know how has he been doing? Ask him how things are going?
