I'm having difficulty believing my girlfriend when she says she loves me its only been 6 wk that Ive been in a?

relationship with her.She left her husband for me'she was leaving him anyway she said I just sped the process'.Shes got to my daughter and tells me all the time how amazing I am.So my question to you guys is,am I just paranoid and that she does love me or am I right to doubt her words that she loves me?
