my bf can NOT emotionally handle sd13.

first, he agrees to let her spend the night with a male friend.

next, sd pulls me aside and tells me this:
"daddy thinks he is 15. his mom thinks im 16. he is actually 17 almost 18. if she asks, will u lie for me?"
of course i said no.

male friend and his mom show up. mom asks if she is 16, both bf and i say no, she is 13. mom says sd can still come and hang out, but cannot spend the night. sd goes in house, slams door, bf goes in after her, mom and friend wait in car. i guess bf called sd a whore.

sigh......so sd goes to friends house anyways, and bf makes empty threats about grounding her, going to text her and say mean shit for lying....

i dont understand how he could be a good parent to bd5, but sd13 he could never handle? i dont know what to do here. to be honest, if sd wasnt in the picture, things would be better here. when she is at her bm's, the calmness of the house...omg he's like a different person.
