CheatingWatch this thread
She chose to get sexually involved with several guys over the last 2 years and now has to decide what future she wants & with whom.
Best not to get closely involved with her.
Nor let her believe that she can keep treating you like a dustbin and you will constantly stick around for even more of her rubbish.
Otherwise you could raise your cuck game, apologise to them both and get to work providing for them.
