I have been with my girlfriend for 3 years. We have hurt each other in the past and she stopped showing me affection. Of course it still a lot going on in our relationship. We have a problem with communication, and we argue a lot. What to do? I feel like she doesn't love anymore.

Talk to her - there's nothing else you can do. If you can't communicate, go to counselling.

How old are you? What are you arguing about? Why can't you just talk calmly?

No communications, no relationship! Not a happy healthy one at least.
