Needing some advice about my relationship? Please help?

Okay, let me be brief as much as possible. My boyfriend and I have been together for almost 5 years now. Just recently, he lost his father. We will be burying him this Saturday and in their hometown. My boyfriend dad is all he has left, very close to his father and taking it very hard. He is in his hometown visiting and making arrangements. We speak to each other throughout the day and sometimes he takes his anger out on me and then he can be very loveable....Two weeks prior to his father passing, we had got into a huge argument and little did I know, he got rid of some of my new clothing that I had purchased to get back at me for something I cant even remember now. Last night, when I confronted him, he act like he didnt hear me and ignore me and lost connection. I have since then called him several times to talk with him. He has not return my calls at all. I know that he is going a rough time and I am trying to be supportive, but its hard when he is pushin me away. On any other given day, I would have went off on him for gettin rid of my stuff, but that's material things and can be replaceable, but I dont know what else to do. Is it over between us? Should I move on? I dont want the best of my insecurities to get the best of me, but I have to wonder, why he wont return my calls? why his voicemail box full? who is else is calling him? Is he seeing someone else and not man enough to tell me? Should I stand by his side and go to the funeral? I dont know. I love him and want to be with him, doin the stuff he doin aint cool neither. I don't know, I haven't lost a parent. Ughhhh Any advice?Needing some advice about my relationship? Please help?
I think you 2 have issues that were unresolved prior to his father's death...and i think he is busy dealing with the death of his father...which is very difficult...and worst if you were close...and he needs a little space for the most part....i think because you were on somewhat ok terms prior to dad passing away....i would go to the funeral..and honor the father he loved...i think a beautiful flower arrangement...needs to be purchased for the funeral...and he may just need a card...saying ';I know this is a difficult time for you';...it's simple and it's understanding what he is experiencing...now...other issues are just that...and he was angry in the past and destroyed personal items...you 2 have other issues...so i would want to invest some thinking time into you.....yes i think after the funeral...you need to step back a bit....and focus on your life education and career....no guy will give you any of those things you'll need to work for them to secure your future....now i wouldn't bank a lot of time into thinking why he is not answering...etc...work on you...but honestly sweetheart...you need to know in your heart that this is not the cup of tea....and someone who respects you doesn't trash personal property....he would call and say i am busy planning a funeral and i am miserable...please let me call you... now you 2 may be fine after the funeral....but you need to do a lot of talking and ...move on to a better space and time.
