i used to put so much importance on monthsaries..Maybe it was because most of my previous relationships were so short-lived..Pero sako bf karon, we've decided to put the big stuff for our anniv and just let the months go by..He doesn't forget to text me good night though..And that's enough for me..
As for your situation, think about how he is in the past..If from the start malimot na jd xa, then maybe he just thinks that monthsaries are petty stuff and that there are more important things than that like programming perhaps..
Btaw, talk with him about it..If he wants out, then let him go and save yourself so much trouble worrying about him and how he is..
