Lonely

When a girl is in a relation ship with a man that is still with someone for 12 years... At times it gets lonely when she got with him she did not intend in falling in love but it happened.... Going on two years now and I'm here home alone all I can think about is he with her or another girl like me he says he loves me yet he has not text or called all day...more info should I go on??? Do you want more?
