boyfriends children being the deal breaker

anxious

my ex and i resently got back together. when talking through our break up issues he informed me his biggest issue was my not talking to his kids.

i knew it was an issue & was trying, but it must not have been good enough. i admit i am not comfortable with kids. i love his kids and would love to have the type of joking easy going relationship i see others have, but can't seem to break through the fear.

now it feels like it is a 'requirement' and he will be grading my performance to see if i'm good enough to stay together with. which makes it that much more frightening.

does anyone have any suggestions on how to bypass the fear? i have to spend time with them for the first time this weekend and am so nerves i'll probably puke...which will make a wonderful impression don't you think?

i'm open for any suggestions. please.
