How offten do you second guess your love?

Well… I only second guess it since I’m very protective and I don’t want anyone to steal my man away from me. I love him so much, but, I can’t really say since he’s usually alone and all he has is usually me and our best friend Alexa…But I don’t really second guess my love for him. I know he sort of does since he’s told me and he’s still sort of surprised (even though we’ve been going out for a about 4 months now) But do you second guess your love at all?
