There are type types of guys who get called nice, sweet, romantic, and charming

If you're in the first category you must avoid being called "nice" and all of those similar adjectives like the plague. I won't go into detail here, we already know.

If you're in the second category (high SMV) being called "nice" means you're starting to make it. Embrace this compliment. Too many guys fear this label and become assholes for no reason (used to be me early on).

I've noticed women have been more frequently calling me a "such a nice guy" or "romantic" or "sweet". This is not because I go above and beyond with nice guy traits, but because of SMV. When you become a high SMV man, the smallest gestures make you become "nice" and "romantic". So, if women start calling you nice AND you are high SMV, embrace it. Don't fear being called nice. I remember one romantic gesture I did for my ex-LTR. It actually was romantic, but it left a mess that she ended up cleaning up. In the moment, when she perceived my SMV as very high and when she loved me the most it was very romantic. When the relationship soured, my actions were seen as being an asshole.

The past 3-5 dates I've been on, I've closed on the first date. After I close I do the some marginally "beta" traits. Mainly because I like to, and because I'm pretty much sure I will never have a false rape claim. Things like, walking her out, calling her a taxi/driving her back, cuddling after sex, etc. But am I actually very "nice"? Nope, I'm just not an asshole. For instance, I enjoy cuddling and like when girls sleep over. One of the main reasons why is because it leads to sex all night and in the morning. My cuddling and being called "nice" is very different from a beta cuddling all night with no sex and being called "nice". If I were so "sweet" I wouldn't close in 15-45 minutes of our first date and pound them all night.

This is very similar to when a hot girl does things for you, you perceive their actions as much higher value than if a fat girl does it something for you.

Conclusion

Once your SMV begins to rise, do not fear being called nice. You'll notice that the smallest gestures you do will make you become "nice". However, SMV aside, it is important to understand what "nice" means and what context it is being said. If you have invested very little and get called "nice", you're golden. If you've invested a lot (especially with no action) and get called "nice", you're viewed as a beta.
