i usually date older guys who feel like they have "been there done that"and ready to settle down.
you should continue to date until your 100% sure, so sure that it doesn't have to be a question, that your ready to settle down,and you feel deep down inside that this person is the one.
my ex of 5 years was confused our whole relationship. at the end, he wanted my son and i gone, so he can date. the girl dumped him after one year, treated him bad, and told him the sex was bad. when we had an electric sex life. he cried for me back or to be friends. but i m in a new relationship and happy.
so please be sure when you get into a committed relationship.
