Hi Zena
I think it depends on how long you are into the relationship. Generally speaking it is best to avoid spending too much time together in the beginning (Maybe first few months) and then gradually dedicate more and more time to your significant other. In my past relationships i felt very comfortable to live side by side with my partner after a year or so (But i think that may differ from person to person).
I think the fact that you get annoyed by looking at him or talking to him is worrying. I think first step is to find out why do you feel that way? Is it the way he acts? Is it the way he talks? Do you find him boring or unattractive? Do you feel the need to change him for your relationship to go on? It is very important that you answer this question to yourself before you can continue. How old are you and how old is he?
However I think it is the dull nature of everyday life that dulls things between two people (And sometimes leads to partners taking each other for granted). My advice to you (If all you are worried about is boredom) would be to start doing some new things with your partner. Go on a holiday, travel together, go to places you always wanted to visit, try something completely different and new outside of your comfort zone (try bungee jumping for example)... The new experiences will spice things up between the two of you and you will start seeing each other in a completely new way...
Also i think its important to treat your partner from time to time as a new hot date... Even though you're in the relationship, try dating your partner from time to time and get him to date you, it can be a lot of fun...
Hope above helps!!!
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
