Can your friends have influence over you than your boyfriend /girlfriend like wise your girlfriend /boyfriend will have influence over you than your friends?

That is a key learning stage for all of us. We all sort of realize early on, that in order to have companionship, that we must adjust to get along with each other.

Figuring out who to adjust for, and how much to adjust and how to adjust, can be very tricky.

Sometimes the adjustment you make for one person, interferes with the adjustment you made for another. You might change how you behave, so that your MATE is pleased, and find out that now your other best FRIENDS feel you are dismissing them, or vice versa.

The main thing to realize, I think, is that this IS normal, and that it IS NOT simple. A bit like tending a garden, in a way, or like maintaining a nice lawn: it takes a lot of daily work, and lots of little tasks to do, which might even change every day, but if you put the effort in, you will likely enjoy the benefits.

Are you asking:

Relationships simply = group.

All individuals belong to groups.

Groups influence individual behavior and choices.

The more you identify with one group (the more it offers what you want), the more your self image/identity is related to or dependent upon membership of one group, the more that group influences your behavior over the others.

Difference between most "friend" groups and "romantic love" groups is "friend" groups are always voluntary participation whereas "romantic love" groups always start out as voluntary and turn into involuntary participation due to the natural mating/pair bonding process.
