Compatability don't determine love, just like background don't determine success in life. I get asked a lot how me and mine stand strong because we've been together longer than most couples in our circle. I always tell em put the love ahead of everything and all else will fall into place. I love hip hop, my love don't like that shit at all, i'm a homebody, she's pretty outgoing. There are other things, some big, some small that we differ in, and there are things that we have in common, but the main line is the love and respect from both sides.
When you first tell somebody you love em, most likely, you don't know to what extent, and you really ain't put enough work in to deserve to say those words like that, it's almost like the beginning of professing love is a promise ring. But there's a point where it becomes so strong, all else don't even matter, at that point, you really know what love is. Money problems, disagreements over children, in laws, all that other bullshit don't matter and ya'll end up being in sync with each other. I can't explain, you just have to be there. Nothing like growing together, these are the depths few reach and ain't willing to grind to in order to possess such a understanding. Don't get it fucked up, it is a grind.
There is nowhere where compatibility comes into play because we simply don't see it. Well, I simply don't see it, we just work around the differences and enjoy the similarities, and just wait a while, some of those differences become similarities lol. I remember in shawshank redemption where morgan freeman said "at first you hate these walls, then there's a point where you get used to em, and after a while you need em". Love is like that. Once you put so much into a person, one day you look at em and they represent something totally different, it transcends all that compatibility shit.
@Shuffington said it really ain't a blueprint to making love last, but I disagree, there's no blueprint to birthing a love relationship, everything from match.com to waffle house after the club, I think the IC even produced some real shit. But sustaining it starts and ends with keeping the love first. Doing so gives you a patience and a willingness to understand and remain loyal through compatibility issues, weight gain, fading looks or under pressure, and won't leave you jaded over time like money and/or good sex or other shit that don't hold weight.
Keep it first always. Love tell compatibility to hop his soft ass in the back seat lol.
