Should I wish her on birthday who is making every thing hard to get?

It's been two years. I believe it was only one year with her that went great. Like we share every thing of life. And then I start observing she is sharing less. And asking me less things. It was painful. I was more involved in her.

Things are not good between me and her now. She always gave me excuses. We work on a same place. So I start talking with her again. She ignore me a lot. But I acted like very nice to her. Things were more painful when she hide her another relationship with another guy. She was going out with him. And I was watching them. But i was accepting all these things.... I dont know why. These things annoy me a lot. I always asked her to end this bad communication state all. And let's be good. But she make it very hard for me. She respond to my text very short. I mean, it's almost impossible to bring her on conversation on text. (talking on phone is you can expect rare, and when I asked her out... she gave excuses). Having all these issues, i dont know why still she used to appear some time on text and do forward messages. I have stopped responding/talking to her on text. Saving my ass and self respect which i believe ruthlessly butchered in this failed tries to make a relationship. Since this month start we are not talking.

A lot of time, no communication has occurred between us for 2 to 3 months. Things are messed up. No one is prefect. But i dont know why every time i returned to her. and she accepted happily. But things start occurring again. like she is ready to be start again. but didnt do any thing. and in all this it's only me who is trying to save it. (i know you guys will consider me, that i end up desperate... i should move on)

On her last birthday, when I was very happy to give her the gift. I discovered, that she has relationship with that guy too. And i was just like watching this. I called her and told that I dont want to continue. But after this I went back again. And been spent a painful year with less reciprocation.

After a week there is her birthday, I am not talking to her. I am walking away. She is not realizing my feelings, my time and just used to ignore me. That I believe against having a good respectful relationship.

BUT girls and boys tell me, should I wish her on birthday?

no. having been in your shoes before i know how it feels to be ignored and treated poorly by the person you love and care about. why would you want to reward that treatment by wishing her a happy anything.

don't say anything to her. just continue to ignore her and if you feel an urge to celebrate on her birthday, do something nice for yourself and buy a gift for you - - that's what i did instead of contacting my ex on his birthday
