How much is too much when it comes to sharing your relationship on social media?

Its up to you. Some people share a lot. Some share a little. At the end of the day its up to you to decide how much you want to share. Most of the time its nothing but lies anyway. That's why when i see those posts saying "my wife" looks good . They have a picture of themselves as their avatar, so I always tell them post a pic of the 2 of you together. You have no problem posting her half naked then you shouldn't have a problem posting her fully clothed with both of you as a couple.
