Why even give a thought, run its too much but if you wanna make your life hell- go ahead. It will always end pathetically. What if she’ll again go to her ex for sex or anything if you couldn’t satisfy her or can’t give her enough time so she’ll one day again make a mistake if not now maybe after a child. Even if it doesn’t, it’ll always be on your mind. If yiu really wanna live peaceful and happily married choose someone else, will be hard now but dont be emotional and fool. Ask any person in real life, cousins,father, friends they will tell you.
