Would it be to extreme to leave him because i need space?

The by-line says you need space, the text is all about his fidelity, or friends. Which is it? If he is married and loves you, you know it, and if he is flirting and having affairs you know that too. Sounds like he is, and you know it. Space is something you might need as well. Marriage is something that you do not take lightly, and if it is that he can have no female friends other than you, then you are doubtful of his fidelity. Go get your space, see what he does or says. and then decide if you want someone like him. Personally I think facebook is not a social website, and if you need a personal page when married, you need a personal divorce attorney! Agree to delete your facebook page and start one that you both are listed as a couple and accept friends together. Enough said!
