If I were an agony aunt I'd advise her to cut her losses.
Frank Lampard always has an excuse to not marry any of his women folk.
I would assume that if you are getting married in June, and it's now April, that you have venue, caterers, planners booked. The dress is ordered the suits are pressed, the flowers being specially grown.
The excuse that Frank is at the end of his contract and doesn't know where he will be playing next season (and lets face it, football ends in May, new season starts in August) there is no viable reason why you can't have a June wedding.
Christine, he's never going to marry you. You are too old to be hanging round hoping. So if you want a family, best you move on.
