Feel single but I'm not

Matilde
So we usaully hang out very often like 6 times a week or somtimes  all 7 days but lately  it's hasnt been like that  lately  I saw him on the weekend and  haven't seen him since then we still talk on the phone and txt all day but then I start to feel single. I'm I the only one that feels like this ?  I really don't like it
