well, i would say don''t be disappointed when things do not continue ''as perfect'' as they have been up until now. honeymoon phases are common and while they are wonderful while you are in them, soon reality and the day-to-day of regular life will set in at some point. i was reading an article about why after years of marriage or togetherness people change and grow away from each other...and it was basically saying that at the end of the day when you ''get used'' to your mate and having them there all the time, it is very easy for them to become ''one more person who wants something from you''. it takes work to not let that mind-set creep in slowly over time.
try to remember every day why this person is special to you. how you fell in love. notice the small things they do that make you happy, that are considerate of you. don''t hold a grudge. i don''t say ''dont go to bed mad'' because sometimes you just need to sleep something off and the next AM things look rosy again. but i will say ''don''t sleep in another room or on the couch'' kinda thing, because i think it''s important to be together in the same room and bed even if you aren''t totally loving each other right at that moment in time. also don''t let small things get to you, aka how he doesn''t pick up his towel or leaves his dish in the sink or whatever. that''s not why you fell in love with him.
so i would just say, definitely be realistic about things...that nothing stays ''perfect'' forever (and it''s okay that it doesn''t!), that way when something does happen to topple the relationship off that pedestal, it won''t be such a big deal...it''s just part of the nature of progression of relationships. the most important thing is that you found the right person for you and you are joining your lives together. that''s the big picture. you will have ups and downs through life. everything else is just peanuts.
have fun!
