This is not to say your partner is having and affair. But what do you think the signs would be if your partner was having an affair. I was once told by an elderly Irish man "Relationships are not like the old days, their not built on trust". Whats the difference between now and then i thought, then i heard him say. "This generation are bound by mobile phones, in the olden days there was no such thing as mobile phones, you had to build your relationship on trust.
