Soooooo, time will prove!! When she returns and the status of U2 remains status quo, u then worth consider what will be your next step!
May be u have new GF at that time or she may have married aboard!! [I heard some BG whom I knew went to UK and Canada for work ,had eventually got marry over there].
Frankly speaking, PRC MM comparatively "materialistics" or "realistics"! But yet there are exceptions!!
Take it easy, man!
