Is this a case of sexual fraud or rape or something else?

You have ”Blain” who always practices safe sex with his g/g of 8 months ”Julie”. Julie really love Blain so she believes and do not want to ever lose him to him to any of his exes. She invites him over and they have drinks and get freaky, the 1st part of the night all goes well and he uses a condom. Later for round three she keeps plying him with hard liquor which he don’t usually drink and get him pretty wasted, she then has sex with him without the condom on purpose because she knows she can get pregnant; and she does. What becomes of Blain? If he
• Doesn’t want to be a father is he on the hook for support?
• If he wants to be a father is the only way to get custody is to file charges against her for rape?
• Even though he did so willingly more or less does it count as rape even though he was too wasted to know if he was practicing his usual safe sex or not?
• Could he sue her because she knew he always practiced safe sex and violated his wishes when she got him drunk enough?
• In spite the fact she took advantage of him drunk or not he is just screwed?

What do you think the most likely outcome would be?
