Dear Girl Who Needs To Stop Waiting Around,
I'll keep this short and sweet. If you opened this, you are probably in a situation where you are waiting for a current or former significant other to come around. You spend all your time thinking about them - what they're doing, who they're talking to, what they would think of your outfit today, etc. and you've consumed yourself with the idea that they are coming back and that things are going to be the same as ever. Stop.
Right now you're right in that with effort from both sides, things could probably get fixed. The thing is, that requires effort from both sides. You can't carry all of the weight forever. And, even if they do get fixed, there is a slim chance that they will go completely back to normal. The best advice I can give to you is to stop worrying so much about someone who isn't focused on keeping you around.
Another thing is stop crawling back. When they text you and tell you to come over, and you get that feeling in your stomach telling you it's a bad idea, say no. They will continue to play with your head to get what they want because they are confident that you'll come back every time. Get out, and stay gone.
Stop putting in so much effort into people that don't return it. They aren't worth your time. If they really cared about keeping you around, you wouldn't be feeling this way. That isn't how someone is supposed to make you feel. Focus on yourself, and the rest will come. This too shall pass.
Sincerely,
The Girl Who Waited Around
