how to like my girlfried happy?

Hi! I f you really love her then you should learn to please her. grant her the requests that she asks you if it's possible. You also need to spend time with her, do things together, talk about everything under the sun. Basically, you to show your love for her in action and not just in words. Your gf will appreciate your efforts once you do that then she will not complain anymore, :D

write her/ him a romantic poem and kiss, lol
