Quoting Mama Rice:" If a woman sleeps with a married man (separated or still married) and gets pregnant but the man goes ... [snip!] ... visitation. The baby is 4 months old and she refuses to let him see his DD unless it is at her house without his wife present."
If the DNA results come back and the child is his, No court would grant her that, Without serious evidence that there should be reason to. Sounds to me like she is really pissed he went back to his wife, And thinks cornering him at her place might see him get back with her, Or at least carry on with her, Or create issues between him and his wife. Personally i think she should be glad that this man wants to take care of his child and provide for it, She's very lucky he wasn't just some smurf that walked away completely.
