Lying "Do the small ones count"

Okay. I love the man I'm with unconditionally! He loves me too...I mean if we didn't love each other we wouldn't be trying for a baby. Just one thing is bothering me. He lies...over the smallest things and thinks I won't find out about them. Such as saying he filled up my tank with money I gave him and saying it took the whole $20 when in reality he put $10 in and bought himself something and thought I wouldn't find out. Another one is how much he watches porn. it's almost insulting because we have sex 2-3 times a day!!! Do I just overlook these??
