A little reminder from a throwback post of mine:
Excerpt: …know that when you’ve met someone who will be there long term, you won’t NEED to look to your right or left to see if they’re still there. You would simply go where YOU want to go and trust that that person will turn left when you do, and right when you do, because THAT person desires to be there too! It won’t be because they want to see eye to eye with you, but they TOO are simply following the will of their heart.
Try not to beat yourself up having stayed with someone for so long that does not make you happy. They certainly must have made you happy at one point, but if you feel a shift and it just isn’t working anymore, listen to your gut about the situation, what is it telling you?
