<human>: Give me the gist of the text in a nutshell

Typing this out makes me realise how ridiculous this sounds.

I've been with boyfriend for about a year now, early in our relationship he confessed to still having feelings for a girl he was once in love with, since then he has reassured me loves me, and is over the other girl. There's no much detail to go into, but for my own reasons, I know he's being truthful. 

Sometimes I get the feeling he's trying to turn me into her. He tries to persuade me into liking similar thing she was into (even sexually), having my hair the way she does, and hints for me to have a similar attitude.

He obviously doesn't say " do this like she did " but I know the girl, and the things that he suggest, are always somewhat similar. 

Baring in mind, they did have a lot in common, which is almost the opposite when it comes to him and I. I'm not complaining on that part, it's fun and being so different just makes our relationship more interesting.

I tend to be really realistic when it comes to these things, but this is something that I just can't seem to wrap my head around and think whether I'm just being paranoid, or there's actually something there.

P.S Yes, I have thought about talking to him about it, but a. whenever something relating to this issue comes up, my brain doesn't seem to realise till later to I should of said something, b. bringing it up out the blue seems a bit excessive, c. I know that when I do bring it up, I'm going to have a hard time not hurting his feelings (I am very blunt when I come to speaking my mind, and I wouldn't want to poke an old wound)
<bot>: Anyone out there have some advice, any input or an opinion for what I could do when I notice my boyfriend trying to change me into a girl he use to love
