Not Motivated in my relationship.

Relationship Troubles. I know, but ever since my relationship with my boyfriend started (December 20th 2016) I feel like every time I say "I love you" I feel like I don't mean it.

And I have trust issues since my last relationship with my ex boyfriend who was abusive. (October 20th 2015)

So How can I mean I love you or mean what I say? He was the first guy who's treated me right and me not meaning I love you to a guy who is sexually and Emotionally attached to me makes me feel like I'm using him. I don't want to feel this way.

Plus I'm the first girl who has not been sexually attached to him. How can I stop this bad feeling?
