Seemed as if things were too rough for me to handle for a while and
BD and i weren't going to make it.
We pulled through and seem to be really happy now. Communication has returned to normal but we still have our odd arguements here and there.
Whats was up with it though. It seemed as if what was supposed to be one of the happiest times of my life was tainted by constant bickering?
Is this normal??

I think it's hard to give you an answer without actually being in the relationship, however, it's perfectly normal to have arguments and disagreements.
It could've been a number of things, increased stress for whatever reason, would stress both of you out. This could cause you to be on edge all the time, or him on edge all the time. Maybe just little things built up and you were both getting angrier and angrier without noticing until it blew up. Perhaps you were both scared about the future, and took it out on each other. Or maybe you were both just plain annoyed with each other, trust me, that happens!
I'm glad things seem to be back to normal. It is normal to have disagreements here and there, and I think the best way is to talk it out, no matter how hard it is.
I just want to add, that if your arguements escalate to verbal or physical abuse, then you need to re evaluate your relationship, and seek outside help.
i cant really say for your relationship. cause i dont know all the cercumstances however for my relationship. we fight sometimes. we get mad , sometimes i hate his stupid ass then others i love him. we both get stressed and forget we liked each other at all. having a kid makes things extra stressed. i blow up on him and we make up and he blows up at me. im with bear bear, if it ever gets physical or the language gets hatefull or degrading, thats when you need to say " whoa" or if you unhappy all the time. fighting is normal.
