should I give up??

Aminda

my husband and i have been ttc for 2 1/2 years. i already have 2 kids from a previous relationship (10 &8). SO won't go get tested and the dr said they don't see anything wrong with me. at this point I'm thinking my kids are almost grown, lol; why start over? I don't know if he really even wants his own kids. he doesn't seem to really care when i try to talk about it.
