Best ways to make a girl happy....
1 of the most important, is to be honest and upfront with what you looking for or not, whether, she will agree to it or not is up to her, but if you don't do this then you in for a whole load of trouble.
2 call her unexpectedly, if you want to, just to say hello to her let's her know u thinking of her
3 even a minor unexpected, small gift, like example, you know she likes Dr. Pepper, buy her one, she would be thrilled, little things do count!
4 take interest in what she does, ask her things related to it
5 do call her back or send her msgs when u say u will most women don't like when u don't call back or respond back to them (seems as if you don't care, or with someone else)
6 just be yourself! always be true to you and the same let her be who she is don't try to change or fix it!
