With regards to the red heart, I myself would not necessarily make much of that, but somebody else might, and that somebody might be your husband.
But, I would also not send a red heart to a friend. Or anyone else, for that matter, simply because of my boundaries, and what a red heart would mean to me if I sent it. I would send them only to my children, siblings, wife, parent, and to be honest it probably would not send one to any of my siblings.
Years ago, many of my colleagues had begun to use Facebook as a way of connecting, and a cheap method of advertising to some degree.
So, I looked into it, my FWS already had an account. After establishing the Facebook account, I did not use it for the business. I was concerned that customers, or their family members, and their posting and messaging, might become innappropriate at some point. After I learned what I could, about Facebook, and how it worked at the time, which was quite a few years ago, it just looked at me like it was going to be a lot more trouble potentially than value. I just saw red flags all over it.
Specifically, I was concerned about female clients, or the female relatives of some of my older clients. Several years before, one of them had pursued me, and a couple of married female colleagues had previously been inappropriate, and Facebook just appeared to me to be a cheater/stalker paradise.
Even LinkedIn, which I have an account on, is apparently used for dating and hookups by traveling professionals, per one of my siblings who is one of those people who has to travel a lot. So, even there, I am very cautious.
