My boyfriend keeps flirting with other girls, when I confront him it becomes a fight cause he doesn't want to own up even with evidence what should I do?

One of the best ways to deal with a situation like this is to honestly ask yourself a few questions. How do you feel about him flirting with other girls, assuming he won't change? How do you feel about him ignoring your concerns and feelings even when you bring evidence with you? You can definitely try to lightly bring up the situation and allow him to take it upon himself to change his actions to better your relationship. He may be feeling overwhelmed and in a state of denial because of guilt or embarrassment. But, always remember that your feelings are completely valid and you deserve to be heard no matter what, especially with somebody you care deeply about. I have had similar problems with my previous boyfriend, and at the end of the relationship I realized that it simply was not worth it to stay in a relationship where I have to ask myself if I'm overreacting or maybe that it's my fault for not being good enough. Everybody is good enough and always remember that you deserve nothing but the best. I truly hope things get better for you with or without your current boyfriend. You deserve to be treated with respect and honesty, so don't put up with anything less! I'm sending you my best wishes and hugs!
