This is just my opinion although i’ve read about it in books, i think is was “Men from Mars, Women from Venus”
Under “Signs Of A Unhealthy Relationship:” i feel that “Giving in order to receive” can be explained from another point of view.

1) When you give, in a normal situation, the person receiving will be feel good and in normal situation, the person is likely to return the favour which will make urself feel good.
- Giving can be anything from being nice to him/her, respecting him/her, doing things wllingly for him/her)

2) Being the first to perform the act of giving. I’m sure tat most r/s in the beginning are all honey coated but of coz, along the way, some of the honey drops off. But if you follow (1), it can become a cycle.
“I make him/her happy who in turns make me happy who in turns make him/her happy ……………”

3) Of coz i’m talking about a near perfect situation. And of coz, giving, in this sense is through pure willingness. Although i’m explaining pretty technical but it’s about giving willingly and not expecting any returns. But in a normal situation, the favour is usually returned. And when the favour is returned, you will be able to continue to “give”

4) After writing all this, i notice tat under “Signs Of A Healthy Relationship:” you wrote “Happy in giving and receiving” which sort of mean wat i had in mind. =X didn’t notice it at first…
