How to respectfully reject someone?

So I have this teammate, she went through a ugly breakup. She currently wants to enjoy her single life. Maa team lo okadi bday party ki velam. Akda adi maa parents love marriage ki okay antunar ..kani nake rasipetti ledu ani edustu kurchundi.

Aroju nunchi maa TL tanaki tega try chestunad anta ...infact dini vala maku konchem benefits vastunde..Edo harmless flirting ankundi tanu but recent ga tana bday ki vadu costly gift ichadu..she realized it was serious and vadini confront chesindi..then he proposed her. Then she told him that she is not into dating or relationship ani. He said okay then...let's directly marry. I will talk to your family anadu anta.

When She told me this.. I told he looks like nice guy.. maybe you should give it a chance Anna. It's been a month since that

But indaka she said he is nice guy but I am not able to catch feelings for him. I am trying to make him understand but he is not stopping ani cheptundi..chats chupinchindi...vadu para raste ime one word reply istundi... morning text cheste ...night reply istundi. Indirect vadiki hints istundi..choostuna nake artham avtundi her replies are so dry ani.

Poni face mida gattiga chepesay ante vadu TL kabati chepalenu antundi. Mari em chedam ankuntunav ante elago maa intlo valu chustunar...direct ga vadiki card ista..ani antundi.

Naku ee advice ivatam istam ledu but...do you think what she is doing is right ?? I just want to know how to respectfully reject in this situation ani...like if you are in place of this girl miru em chestaru ?
