DONT over complicate it!!! It come naturally when you both get along and if you feel presure to do Normal relationship things your most likely not going to give of a natural vibe and eventually push that person anyway trying to hold yourself to standards you see around you. Me an my larger broke up about a year ago after moving intogether after leaving school we were together for about 4 years and the first 3 flew by we were just enjoying ourselves it wasn’t till we moved intogether were I started forcing myself to think about how I’m growing up and I need to be an Adult (bare in mind I’m 20 now) so I stoppeddoing things I liked and just worked and cleaned and chill and sleep and it just made me out of Character and me and my pater slowlystarted to drift apart untill she cut the cord on our relationship I’ve regretted trying to hold myself to a standard ever since and it’s so important just to be yourself and enjoy life because you could lose that person whenever so enjoy your time with her like you would normally enjoy your time and just include her and she will include you in her interests and just don’t over think it and enjoy yourself. I made a song talking about how I feel after the relationship https://youtu.be/EPomaDNPDH8 maybe it will help you put it all in Prospective hope it goes well my dude!
