Hi Tori. When we have someone suffering from cancer in our family, there is an alternation of mood among all family members, especially those who are directly involved. I was the carer for my wife throughout her treatment, which lasted ten years. My relationship with my mother-in-law and my brother-in-law alternated because sometimes I was relaxed (because I knew my wife's conditions) while one of them could be anxious or very nervous sometimes only because of chemo side effects, sometimes because of how she suffered with certain chemo agents or only by a change of our own mood. It's hard to know what the days will be like. Unfortunately we can not change the course of things, we become depressed when we do not have control of the situation. All we can do is try to give the patient a calm environment where he does not feel a burden for the caregivers or the family. This sometimes costs us some hassle with other caregivers or loved ones. Giving room to your boyfriend and his family is a good thing but always be around because he may need you when he feels down, wanting to hear a word of relief and then, I'm sure you'll find the ones that will make him feel better. Best wishes
