So Cox tells Jordan how feels about her, she says that he would have to behave differently -he doesn't and she leaves him.
She turns up pregnant, saying she can't have the baby alone and wants to get back together with him -and he just submits like a lapdog?
Yep -being a cuckold (as far as Cox knows) and a back up plan is exactly what most people with even a semblance of dignity would do. . .totally realistic.
