Like others here have said its natural to be homesick and it is tough on the Guy also as your not sure what to do. The Wife went home recently on a trip on her own back to Phill for Easter for three weeks.
Once she is there she was missing the Uk, her friends and Me, but happy to be in phil with her family and friends. Its natural for a women to be like that it appears from what i read on here.
With you looking after her and giving her a Wonderful Birthday Weekend.
So i guess its natural and shows what loving ladies we are married to who cared and love both us, their friends and family so much
