Dang.. you were together since you were 18? I hope you can work it out (if that’s what you want) but as someone who dated a lot, had a lot of long term relationships, and waited until 30 to get married... sometimes the person you were attracted to in your late teens isn’t who you’re attracted to in your early 20s, sometimes the person you were attracted your early 20s isn’t who you’ll be attracted to in your mid 20s, and sometimes when you go through the deep pain and fear of leaving a person you love and stepping into the void/unknown future alone brings you to the person you can have a fulfilling mundane, exciting, sex, romantic, and partnership life with.
