My boyfriend's mood swings affects us

My boyfriend and I have been together for a short while, I love him with all my heart, but he has these mood swings that really upsets me and sometimes upsets our relationship with each other. I know that he loves me and cares about me but for some reason we just can't seem to get along. I don't think I hae ever had these problems with with someone especially in the early stages of a relationship. We are so upset with each other but we try not to let it show, I really want our relationship to work but I'm afraid that all this arguing might be a terrible thing for us. Is it common to have these problems in the early stage of a relationship? And how can I make it work?

**Every couple has arguments. But if your arguments are over stupid things, it generally means the relationship isn't the best. When the two of you feed off of each others attitude and make life difficult for others, that is another sign that you should end the relationship. If it doesn't make you happier, feel better, and content, it's not worth having.**

Heres some info I found on the subject>
Why Are Some Relationships So Difficult?
*Ever heard about how it's hard for someone to love you when you don't love yourself? It's a big relationship roadblock when one or both people struggle with self-esteem problems. Your girlfriend or boyfriend isn't there to make you feel good about yourself if you can't do that on your own. Focus on being happy with yourself, and don't take on the responsibility of worrying about someone else's happiness.
*What if you feel that your girlfriend or boyfriend needs too much from you? If the relationship feels like a burden or a drag instead of a joy, it may be time to think about whether it's a healthy match for you. Someone who's not happy or secure may have trouble being a healthy relationship partner.
The key to a healthy relationship is communication...you can be happy, sad, angry, joyful, you can own all these feelings but what you do with them can make or break a relationship. What ever the feeling is you cannot expect your significant other to read your mind... you can tell him/her using "I" messages in a non threatening way as a means of communicating what is wrong and very important here..what is RIGHT...so often we complain about what is wrong but fail to celebrate what is right...
In a relationship, two people should be constantly growing...together...they should be sharing ideas, hopes dreams...the hope is that you grow parallel and not apart...and everyone needs his or her own space...if you are emotionally happy you will not be threatened by your partner needing time away or from asking for time for yourself,
If your friend or person you are dating loses his/her temper a lot and always blame you for things, This is a sign that your relationship is unhealthy
In a healthy and safe relationship, each person takes responsibility for his or her feelings and actions. You should never have to worry about getting yelled at by your friend or dating partner, and you shouldn't be blamed for everything that goes wrong in his or her life.

I dont know if thats common for early in a relationship.. all depends on the type of relationship you have I guess. are your fights really worth it or is it just over stupid stuff? because everyone argues right, it just depends what its about and how its done. if theres name calling or harsh things being said than its not a healthy relationship. have you tried just talking to him about it and suggesting some ways to fix things. if you guys plan together it could help.. otherwise your fighting may get out of hand and you'll split up. constantly feeling upset isnt good sweetheart, not for either of you.
