Welcome to this part of the DB world Wanted. Sadly, our numbers are growing. Promise we are lots of fun though.
I appreciate you not wanting to hurt anyone but I think it is unavoidable in this situation. You have to be honest with her and the sooner the better. She’s probably already checking out baby clothes in the local department store. If you have truly decided you don’t want to have anymore kids, and it sounds like you have, than you need to let her know. After that...the ball is in her court and she can decide what her priorities are. (((HUGS)))
