my girlfriend flirts online and i love her to death, what do i do?

[Bit]

i used to be a huge flirt. I always told my boyfriend it was harmless and that it wasnt cheating. He told me it was disrespectful and i had to choose between everyone elses attention or him. I chose him. Been together 5 years and i dont regret that decision. Looking back and self reflecting i realize that was my way of feeling good about myself. It is truley a reflection of low self esteem. If she still needs every other mans attention she still needs to grow and "Find herself". Until she realizes that your attention is enough you will always wonder about her. No one deserves to be treated like that. Sorry.
