I met my husband when we were teens, so that might explain my patience. I didn't find a guy whose manners suited me. I found a guy who had similar values to mine and a great personality. Then I communicated with him:
When he sniffed during a meal, I gently suggested he go to the men's room and look after his nose.
When he overspent on a gift that made me uncomfortable, I explained how I felt and he returned it and got something suitable.
When he lived on his own and the cleanliness of his apartment offended my sense of hygene, I helped him clean up once and told him how it made me feel to come to a filthy place. He didn't have to be told twice.
And he did the same thing:
When I had my hair cut short, he explained that he liked it long-no matter what.
When I was too affectionate in front of his friends, he explained how it made him feel.
When we were first married and I spent our money without talking to him first, he told me how he wanted us to share our finances.
Guess what? He became the perfect guy for me and I became the perfect one for him! We've been married 22 years.
If you are expecting to meet someone and have him tailor-made for you, you are going to be sadly disappointed. In every relationship you need to be able to give and take correction. A man with manners that don't suit you can be gently corrected-he isn't a loser to be ditched.
