My husband has had an emotional affair with women for about 3 years.?

the first time I found out was by finding text messages and he said that it was a guy so he lied about it and when i kept confronting him about it he soon confessed and told me that he wasnt going to talk to her anymore a few months later i found out that he was talking to her and another women and again he told me he was going to stop and that he was sorry since then ive caught him againg about 4 or 5 times and everytime he got caught he was sorry now i fel that the marriage is over cause i dont trust him anymore and hes lied to me so much i dont know what to do should i just leave or try to work it out also we've only had sex about 3 times this year cause i feel the same way about him anymore im just really hurting now
