These ladies are into online dating with decent men from other countries. Some of them don't want to meet local men. They have a goal to live their country. Let's look at the reason of this behavior:
1. Poor economic conditions. In some countries it's hard to give the bright future for your kids. The reason can be materialistic. Many ladies want to live in a European country with better social and economic conditions. You shouldn't judge them for that. At the same time these women would like to meet an awesome and kind man who will attract them. If you have enough money, be careful. Make sure a girl likes you at the first place, not your wallet.
2. The lack of decent local men. Brides may have a bad past experience. Sometimes their local men are quite rude and abusive, many of them have troubles with alcohol. In this situation many women prefer to look for foreign partners.
3. They are romantic. European and American melodramas are very popular in Slavic countries. Some women take foreign men as generous and courteous gentlemen. No wonder they fall in love with these guys! It's your chance to catch an attention of a wonderful woman!
4. They are interested in different cultures. Girls are open-minded and curious. They want to know more about other countries, their culture and traditions. Many of them like online dating because it allows them to learn a new language. In this case you can be friends for a long time before you start something romantic. It's one of the best way to get close with a woman.
5. They are going to move to another country because of work or business. These girls look for someone who will chat with them and will help them to adapt on a new place. It's another best option, because you don't have to help them with papers in a financial way.
