I keep getting text from this number and it just says love you ?
I would like to know where this number is coming from I have never seen any number like  this and it has plus sign 2 in front of the 23448115548961

The plus sign ( + ) indicates that the call comes from a different country.      There is a list of Country Codes at http://countrycode.org/    where you might find one that matches.       I would do it except that you confused me by saying "plus sign 2" in front.
