To the friends who:
change when they get into a relationship.
get jealous when your significant other is with their friends.
leave friends and give no explanation.
Now I know this person might be the one or this person might get jealous over who you are friends with (male/female) but that does not give you the right to blow off your friends.
You can be friends with someone. It does not mean it has to be something more or anything, but you have that one person you told everything too and they just got it.
They were the ones who were there for you when you wanted to go get food. They were the ones who dropped plans to hangout with you. They were the ones you literally told everything too.
And then one person comes along and ruins that, because they might "get mad at you."
"Oh I'm not allowed to talk to you."
"My girlfriend said I wasn't allowed to be your friend anymore."
Now I know there are some circumstances where it would be annoying if they kept blowing you off every time for this person. And if they had a past together I could understand where you would not want them to be "best friends". This isn't the case though.
This is really about jealousy in general, with anything.
(Friends literally being just friends)
If that person cannot trust you with your friends then they are not the right person for you.
I've been around jealousy, I know what it is. I have seen long time friends go to strangers, because their person cannot handle it. It's a sense of control. People are so self conscience that they feel the need to strip you away from your friends because they do not want someone bringing happiness into your life other than them.
Jealousy is an ugly trait. Sure we are all guilty of it, but isn't it exhausting?
Proverbs 14:30 says, "A heart at peace gives life to the body, but envy rots the bones."
I bet you spend twice as much time on your phone looking at what they might be doing or what they could be doing rather than enjoying the moment that is right in front of you.
If you are so focused on what that person is doing rather than enjoying life with them, then it is just going to bring out the ugliness and hatefulness in you.
People need to put more trust into God. The scripture says in Psalms 143:8, "Let the morning bring me word of your unfailing love, for I have put my trust in you. Show me the way I should go, for to you I entrust my life."
Wake up every morning knowing God knows what he is doing with your life. Live happy. No reason on stressing any more about the little things that will not matter in 25 years. You might not like it, but it is His plan for you.
You should be more focused on what God is doing in your life rather than what your boyfriend/girlfriend is doing when they aren't texting you back.
