Keep Girls Interested in *Relationship* "Nice Guy"

Not sure where this is going but bear with me.

Note: this is for DATING, relationships, not first second third dates, etc.

Ladies (and gentlemen) - I have been dating my girlfriend for almost a year now. Things were going great, and still are, BUT. I do feel at times being concerned I am too into her. I know we both have seen a future together. I believe it is important to be myself and have done so thus far. EX. not being "fake" and pretend to be disinterested - just not who I am or how I feel. Know sometimes people will be like oh just pretend you don't give a sh*t. Well - not looking for that type of advice. This is for other guys who have been also named a "golden retriever, the sweetest/nicest, etc.)

There's been less contact and been "busier" work days. Any tips?? help a guy out. (personally am in a LDR with this situation, I think this can be applicable for many guys like me) Thank YOU :)
