Pregnant and scared

I’m in the process of separating from my husband. However we had drunken sex in the wee hours of the 18th of June. Now I stupidly hooked up with a friend a few times that week (we did use a condom) but one or two of the times that we hooked up the condom slipped after he pulled out with the open end hanging out of my vagina. I don’t recall any spillage or mess near my vagina so to speak. I got a BFP on a clear blue rapid test on July 3rd. I think I ovulated on either 6/22 or 6/23. Based on this information what are the odds that the baby is the man that I slept with with mostly protection versus my husband who I had clear unprotected sex with?
