Am asking what does it mean if ur ex starts buying gifts for u on birthday & other days which she didn't do through the love u had with her?
It could mean that she still values you as a friend or she is interested in working out the relationship. The question is how the gifts makes you feel? Are you comfortable or uncomfortable. If you are comfortable you may consider reciprocating by sending her gifts.
However, if this makes you uncomfortable and you don't want to sort things with her, then it is important that you talk to her and let her know what you want.
