My ex girlfriend left me a voicemail asking me how I was about a week ago.

Then she talked to me early on Valentine's Day but her cousin was on the phone with her and the call was short like 5-10 mintues.

Her cousin then called me a few days later with her on HIS phone and the call was short and she barely said anything to me at all-- just listened basically.

I left her a voicemail this past weekend asking her how she was
And she ignored it.

2 days ago I called her phone and she pushed ignore on me and her cousin confirmed this.

(We've been broke up for a 1/2 year now)
How come she can ask me questions/talk to me but she ignores me when I try to call?
