Is it always my fault

myself and my boyfriend have been going out for more than 3 years now. We are constantly fighting and it's always the same thing, no matter what happens it's always the same. The amount of time we spend together alone basically doesn't exsist, his friends are always around and we normally see each other 1 day of the week and weekends, and in those times there's never time for just us, if we make plans he always changes it to accomadate everyone else and i have asked pleaded for time alone for so long and if we ever do get it, his always tired or theres always some reason why it never works out but when it comes to drinking or going out with the guys staying out till early hours in the morning is not a problem. it feels like his embaressed to be with me or that i mean nothing .... i don't know what to do it's driving me crazy and i feel so empty. i understand in giving each other space but thats all we ever do. i've tried just keeping quiet and letting him do whatever he wants and that doesn't even work... so please explain to me what i'm doing wrong....

I would suggest doing some fun activities together, away from the house. Cinema, bowling, even just eating out somewhere inexpensive and having a few drinks. Maybe you could agree a scheduled occurance which you get him to stick to. Start off say with the first Friday in each month, because this isn't too much to ask for is it. Or if weekends are the most precious to him with his mates, then do something midweek. If he is unable to commit in this way and on such a small scale to solitary time together, you are unlikely to ever change the situation. To check whether you are still right for each other, you need to get yourselves on holiday and spend time alone in each other's company for a fair amount of time each day - this can be quite a testing time for some couples, but it helps you find out where you really stand and whether you have equal commitment to the relationship.
