I met my husband last year in July and we were married this Jan. He was my knight in shining armor. I started figuring out there was some issues he was lying about tho

He emailed an ex girlfriend that he still loved her, yeah i have a keylogger on pc, i confronted him about it and he denied doing it. He said he never got on his myspace and yeah i got past that too and found him and her putting lovely i love yous on there too

well he did delete the myspace and told me they only was friends now. All this happened before our marriage. We got married in Jan, I was at his apartment cause we had to move the rest of his things to my house, he had to work, i went to trash can, oh man, ontop of the trash can was a victoria secret bag, a pair of womens underwear ( not mine) and 2 cards from that ex girlfriend ontop of the trash ! I was totally upset. I txt his phone, he tried to tell me the bag was his 13 yr old daughters and the underwear he didnt know where they came from, well after about 45 mins of me not talking, he admitted that they were indeed the ex gfs underwear, he said he found them under the bathroom sink and he threw them away , i told him why didnt he just tell me truth, he said oh so i am supposed to just always tell you truth no matter what, i know that bag and underwear have never been in that place, i have looked over that place before and never been there

I am having a hard time dealing with this, I have lost my trust and i dont want too . I have caught him in alot of lies but if I confront him and I have, he makes excuses for them or more lies to cover the lies. How do I get to trust him again? how do i know hes not lying this time?
