why do people love us when we are doing what they want us to do?

Some people are only taking us for granted. But once they cannot find anything useful or cannot ask any favor from us, they will surely leave us behind. I have seen few people having such kind of attitude that is why I am too keen when making friends esp with strangers.

That's not true love or gratitude. If someone only loves you when you're doing something for them, then they're merely being selfish and aren't worth your time. I agree they need to learn to do things for themselves. I think all of us can sometimes show more gratuity and affection when we're getting something we want...It's human to be excited. However, to do it all the time, and to only show thanks and love when you're getting something you want, just shows you're not an appreciative person. (Or they aren't that is). You just have to surround yourself with people who appreciate you more as a person, and not just for what you do to cater to their needs.

Some people are takers. You have to stand up for yourself. No one else is going to. People with run your life for you if you let them. You teach people how to treat you. It sounds like your not getting the respect you want. You have to change that. If they are truly your friends they will respect that and be by your side. If they leave then they were never your friend anyway. I recently had a friend try to over take something in my life. I let them do it before. But this time I stood firm and said no. It's been a while and no contact from them. I'm ok with it because I won't be bullied by anyone. My life....my right! Make the choice today to stand up for you! You will love the feeling of taking that control back that you gave away! Good luck!
