I'm so frustrated with men i'm rdy to give up on finding a decent man and just get a dog?

guy#1 was a compulsive gambler that would spend 5-10k a weekend at a casino.our 1st weekend away consisted of me sitting in a hotel room alone.the only time i saw him was when he ran out of money and wanted my c.c.guy#2 was a 40yr old alcoholic drug user that spent his whole pay check partying with his friends.my weekends with him was spent with his loser friends watching him get drunk.now guy #3 was the worst yet.he was a divorced dad in debt 30k with a controlling exwife who lived to make my life hell.to top it off he was a chronic lier/cheater who was always sneaking around on the internet and contacting old gfs. after i told him i would not pay off his debt things got sower fast.he told me i could not handle him being a divorced dad.what i could not handle was him after my money and him allowing his ex to treat me poorly and not even care.i feel now "i missed the boat" in my wanting to wait to get married(i'm 35 yrs),now all the good ones are married and will stay married.
