Waiting for an engagement is the hardest thing. I think it must be worse than waiting for a wedding, becase with the wedding you can at least plan. I understand your pain... I am waiting for my boyfriend to propose, and I have a while, because of all the stuff going on in our lives, but what makes it harder is that I am in 5 weddings this summer, and I am helping all of them plan their weddings. I am thrilled to do this, but at the same time, there is that little part of me that wishes that i was able to start planning mine.
Good luck with your waiting, and good luck with the future SIL. I do agree that going from filing for divorce to having a baby is a little sudden, but than I can't really judge. God's blessings in all you do though.
never the bride, always a bridemaid...or a groomswoman....and totally thrilled to help my friends.
