do i still let my husband chat and flirting with ladies in the internet?

I think you really have so much patience, and you love him so much. That everything is just fine. But everything has a limitations. Everything that is too much is bad also. Your letting your husband near temptations. I think you should talk to him about this. What if he falls in love with another girl. You can't tell! Have a nice day to you!

he is there every weekend because he is getting something from them that he isn't getting from you. This could be attention,listener or just something small that you may have given him in the beginning that he misses and they supply that to him. Just my two cents.

I feel really sorry for you. Some people do this just to have fun but they don't realize that they are doing something wrong. Specially if he is a married person he should think that his wife will get hurt by doing this. Recently I joined some places where we could meet friends. I thought only my friends will be in touch with me but to my surprised I was getting 100s of mails asking for friendship and some even wants more than that. Most of those guys were married and having children. They do not hide that they have a family but still wants to have a friendship. What for? I don't reply to anyof those and I simply blocking them so that they cannot send me mails. So dear, I think your husband too might be doing it just for fun. Best thing is to go somewhere or try to do something with him during weekends so that he will not have the time to do it. If not tell him how you feel. If really loves you he'll try his best to stop it.
