Loving someone isn’t the same as being in love with them.
Being in love is the intense feeling at the start of a relationship, when you only see the positive things about the other person and walk around with your head in the clouds. This feeling can be so intense it actually hurts – especially if the person doesn’t feel the same way about you.
The feeling of being in love develops over time, and becomes a deeper, steadier, tender feeling for the other person - you love them.
Love develops in stages, and doesn't always follow the same pattern. But in most cases love begins with the passion of sexual attraction, then the dreamy, overwhelming 'in love' stage, and finally the deeper attachment that develops over time and can last for years - sometimes for a lifetime.
