Praise the Lord.
If the space you're giving him is complete isolation, If I was him I'd would want to know to. But there are discrete methods to get space and still show that person you're their friend.
Keeping conversations nice and short, don't make yourself to available, use text messages instead of voice calls. Sending encouraging bible verses periodically or daily are ways of being present in someone's life yet still maintaining space.
Start focusing on you, and building yourself to be the woman God wants you to be. And the only way to do that is to give God 100% of you. God wants to know, can I trust her with him, would I still get all of her when I give her a partner. Would he steal the attention and time I want to spend with her.
Telling him " I need space, because I like you and you like some else ", is going to make him feel bad, he didn't mean for this to push you away.
It's about you not him, you don't have to go into details in to "why". If it's really bad, then you just tell him " I need to spend a little more time with God, right now, so I'm just giving you a heads up, don't feel like I'm avoiding you or that I don't want to talk to you "
Because honestly that's how it's suppose to be...telling him is like putting your burdens on him, when it is God alone who controls you and has the power to sustain your emotions.
Protecting the friendship, giving God 100% of you, and truly loving this guy enough to let him live.
1Cr 13:4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud.
Patience such a hard word to follow, but thank God we have the Holy Spirit to direct us.
1Cr 16:14 Do everything in love.
Whatever you choose to do, make sure it's done in love. Your actions towards him must be love..and not the results of a broken heart. If love is not involved there is a motive.
Because
21For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23All these evils come from inside and make a man 'unclean.' "
Mark 7:21-23
Father God I ask that you keep this sister's heart in check, remove all the seeds the enemy has planted hoping to produce unfruitful fruits that will decrease her spiritual growth and be a distraction. I ask that you create in her a clean heart and renew a right spirit within.
Amen.
