There’s the issue of being insecure and saying you don’t care, when in reality a part of you actually does care about your girlfriend’s interest in her exes. Your significant other can consider her ex as casual acquaintances that communicate on occasion, but when they remain best friends for life that still need to frequently do things together, they cross the line.

Some can remain an online acquaintance which is fine, but when they begin to make inappropriate contact on social sites, start frequenting for lunch, dinner, drinks or become a nuisance with phone calls it’s not okay.

However, there are also reasons for exes to remain in a person’s life which are due to expectations such as children, leaving you no choice. Many men won’t date girls who still talk with their exes due to two simple reasons: They maybe secretly infatuated with them, and when their ex doesn’t want them, you become their second choice. As well they can be enjoying the attention; in return many men aren’t interested in a woman who craves a ridiculous amount of attention and can’t get enough of it.

Don’t give your girlfriend the choice or thought that they can’t add exes on social networks, you’ll create trust issues. Some couples go as far as giving each other access to both of their Facebook accounts to prevent these problems for ever arising. And while some might consider them being friends online a gateway to start talking again, most just wish each other happy birthday, talk about work and school-related things or recommended new movies or music.

While most will agree this is the typical interaction, there are instances where there can be affection with a flirty or sexual tone in conversions and it’s something to consider. If she broke up with him after a large number of years being together and they’ve spent only a year or two apart, she may end up welcoming that affection from him. Another thing to consider is that while they may be talking, her ex may now be more reserved with expressing his emotions, reminding her how much they’ve changed, and how neither of them can provide emotional support for each other.
