Hi! Welcome to PC!
I hope you will find the information and the support you maybe seeking.
So glad you have joined in.
My advice on your relationship?
I'd seriously consider calling an end to the relationship. In my experience, guys who do this will continue. They are just sorry they have gotten caught!
They are "under-handed"and will continue to operate as such, it is ingrained in their personality!
I agree with the above posters about much! I truly agree with the poster mentioning sex with this guy might be dangerous and you should reconsider having sexual relations with him forever... Or at least until there is much more clarification and, hopefully, involvement of a good therapist.
Please consider getting a therapist for yourself. I truly think you will benefit from the support and any additional input/insights! You deserve this!
Best wishes with whatever you decide!
