Now before I start let me say you can take this post for as much as you want, I am not a marriage counselor...I mean come on y'all know how that is playing out for me. But maybe someone out there who's married, engaged or heck even you single people can take something from this and learn from my..well our mistakes.
So this is what I've learned.
Before you were together you were a total separate person with friends and a life, same as your man. You may not like his friends or he may not like yours, well they are your spouses friend for a reason so support them in that friendship. And he should do the same.
Don't keep tally on things "like oh well I took out the trash and did dishes so you get to do it now, if you have time do it. If you ask him to do it and he gets huffy just do it yourself and don't argue about it...even though that can be hard.
Let him go out on a boys night...and don't complain about it later. He should understand and do the same for you.
Even the closest couples need alone time. Each person should understand that and not take it personally.
Set up date nights or days weekly or biweekly if you can...(we failed at this miserably)
Support his dreams and ambitions even if they seem crazy to you, he should do the same. Now, I'm not saying you should be like "oh yeah quitting your job with benefits to be a clown sounds amazing babe, let's do it" Within reason ;)
Say thank you. I don't think you can say thank you enough.
Communicate, if you are one who will get mad but hold it in and not say something, then something minor comes along and you blow up and go on a tangent, try to communicate when you are initially mad.
When your arguing about something (everyone does, I don't care how "perfect" your marriage is) stay on that subject don't go all off on how a week ago they did this and that....
Don't stop trying. Once your married don't stop doing those romantic things (I guess this is more for the guys) show her that your still interested and trying. Not complacent because you "have" her now.
I had been thinking about this all day. What I've learned from my marriage. And even though it's ending, I still learned things. I learned how I should be treated, how I should treat someone and how to make a relationship work, which is probably pretty much the opposite of what our marriage was like.
Like I said you can take all this with a grain of salt. But I needed to say it.
