Just sharing a little something I learned for myself...
Me and B work perfectly with each other when we talk and can touch us... so many things are unspoken, yet understood and I can show my love in many ways... but when we are separated by long distance, we fail to communicate equally well.
You might encounter this yourself if you hold relationships with people over long distance... being in person is always greatly different then being in person... I have people I enjoy greatly online, exchanging jokes, wisdom and advise, yet are nearly unbearable in person... so it goes both ways.
