Could your people-pleasing side be constantly at odds with your independent side? Could this be the major cause of internal strife and some external strife? Let me explain.
You have a great need to serve and please others. Wonderful! You also have a need to be your own person, at times. Equally wonderful! Yet, you are constantly torn between the two. Your frustration with close relations comes because your “significant others” do not know where to draw the line. They do not know when they've "crossed the line" with you. THEY do not know because YOU do not yet know. Am I making any sense?
You must discover that "line". When you clearly define it for yourself, then you can clearly define it for others.
You need to reserve some time, energy, and money for yourself. Keep some back. It isn't selfish. Insist upon it! These significant others can fend for themselves while you take time off from serving. (Unless they are newborns and, if so, get a babysitter!) They aren’t helpless. If your significant others can’t go a day without you, your relationship isn’t healthy anyway! Are you getting the picture? The world will keep going one day without you to hold it up!
Maybe you want to be a doormat in specific areas. That’s fine. YOU decide what YOU can and are willing and able to do. You also decide when you’ve had enough! Discover the line and draw it! Here’s the kicker.
Once you draw it, you MUST defend it...EVERY TIME! Don't let anyone (not even your people-pleasing side) compromise your line! If you constantly move it, when others start whining and complaining about it being there, then it was useless to draw it in the first place. Because it means nothing. Allow your strong side to defend all necessary lines! DEMAND that others respect your lines!
No border or boundary is appreciated and respected that is not well defended. (There's your solution to the immigration problem!)

Appropriate borders, boundaries and limitations constantly define us to others and to ourselves. We are nothing without them. We get to define all lines that define US. God through the Holy Spirit keeps us from being too selfish. That's the Spirit's job. So, don't worry about being too tough with your lines. (If you are a true Christian who is listening closely to God.)
Listen more closely to God than you do to anyone else. Including yourself! NEVER compromise who you are in the Lord.
