Never go to bed on a argument and forgive each others little mistakes such as leaving the lid off things and not putting clothes away in the cupboard, and spend time apart so you don't suffocate each other and when you're apart you'll miss each other and then your time together will be more special. Also be understanding of each other and don't have high expectations and try to avoid criticizing each other and don't let the compliments dry up after the honeymoon period.
Don't over complicate things, and whatever she cooks all ways say "this is the best dish i've tasted" even if you think it's revolting :heated: be playful and not all ways serious, do the romantic things that the prophet (saw) would do, like when she drinks from a glass put your mouth on the same spot she did, and when she enters the room get up and offer her your chair, don't look at other women at all or comment on other women, actually talk to her and tell her how you're feeling, tell her you love her every night and don't go to sleep without saying it cos words effect a persons heart.
Value each others opinion and don't belittle something she says or does, all ways show your appreciation when she does stuff like cleaning and cooking, buy her gifts doesn't have to be expensive, but the fact you took the time out to do it means a lot, communication is key, don't hide your feelings, if your unhappy about something talk about it in a calm manner when you're both relaxed and if things start to heat up and you see an argument coming defuse the situation by making a joke or doing something silly so you both laugh and avoid the argument :hmm: tell her often how much she means to you and reassure her that there's no other woman you'd rather be with than her, talk about your fears with her and open up to her, don't hide anything at all, tell her how much better life is with her in it and you never wanna go back to life without her, tell her how happy she makes you feel, just make her feel special cos she is, look at how long it took you to find her

do and say these things often, real warm moments.
If you're at work all day make sure you text her at some point telling her you're thinking of her and how much you miss her and can't wait to get home to see her.
above all, all ways be understanding, there's going to be lots of times when things don't go your way learn to accept that in a mature manner, if she's too tired to cook or do something else put yourself in her shoes and understand where she's coming from. She's the love of your life, the woman who completes you and makes you feel like you can achieve anything so treat her the way she deserves and not like the house slave. Don't be a demanding dictator, sure certain things are your due right given to you by Allah but at the end of the day she's only a human and she's going to have short comings, so learn to love her short comings and you'll stay happy inshaAllah.
Also you may have lost someone in the past that you loved, and you try to draw similarities with the new person you're married to, and the person you lost in the past, this will never work because everyone is unique, you just have to learn to love again, you're never going to find someone like the person you lost, but you can find someone else who can offer you the same things and you may even be happier.
I went on a rant :hmm:
