How do you prove a girlfriend you love her?

Try to treat her like you did the first day you met

Ng, maybe show that you care for her, have a clear communication and included some romantic events like having a dinner, going somewhere to spent a time, or a special gift would do..

1. Be thoughtful.

2. Give her little presents that you know would be special to her (love notes, roses, Her favorite candy)

3. Take her somewhere special or do something special

4. Give her a back massage

5. Tell her you love her (can't read your mind and that is showing her)

6. Do the things she ask you to do (like fix something for her or help her with something)

... you don't have to show it.. just be a good respectful boyfriend who never fails to care... make it a little mystery.. let her figure it out.. girls preffer that over guys going all puppy doggy on them...
