So many different emotions...

My boyfriend and I have been together a little over 2 years. We have a 1 year old. We have issues in our relationship, and we bicker a lot but we stick it out and make up for our son. We are just getting back together from a serious split after me finding out he had been lying to me for two years.. I came back because I want our family to work. But this time is different.. I feel like I'm losing feelings or not trying like I used to. I just don't know what to do anymore :/
