What should I say or do in my current situation?

Me and my fiancé finally are almost 100% over our bad fighting phase we've came a long way from arguments every day to every so many days to now maybe one small one every 2-3 weeks but we normally talk things out but we still get a little irritated at each other but we come together and end up talking about it unlike before but ill soon be going into basic in a month and a few days.. I'm really worried about our relationship we've both worked hard to fix things and we both realize we both have had our share of screw ups in this relationship and were just now getting to this part of our relationship where we are better than before we have been dating for a year and a half now and our beginning part of our relationship -first several months have been one hell of a ride for us.. He keeps telling me everything will be okay I know and you don't have to explain yourself I forgive you as well but I wonder maybe it's just that I don't forgive myself and the more I keep talking about it It makes me look like I'm more guilty than I should be but mainly it just annoys him but he understands how I feel how I just feel terrible about the past he has felt the same too and still do sometimes. I just seem to have a strong conscious But I'm not perfect and I'm a lot more open with him and straight forward with him especially and others I just don't know what to do Idk if im just being overly emotional or just thinking too much but i don't want to push him away.. We used to ask each other why do you love me still even after my mistakes I finally found the words to tell him how I felt why I've stayed, he makes me feel like for once I'm seen for who I am not just some pretty face, I feel comfortable around him, we help each other he inspires me to better myself in life not only for him but for myself he gives me confidence and I know he has had his share of mistakes in the past in this relationship but so have I, I forgive him and love him thru it all and love him for the person he is. He says he feels the exact same as well and I can tell by his actions he feels that way but my biggest problem is that I'm worried when I leave for basic or whenever I have to leave something will flare up from our past.. -no not cheating- but I don't want it to haunt us by guys talking more shit to him I had a bit of a problem with that in the beginning a good example is one of my ex's was very annoying.. he tried telling my boyfriend that me and him were still together while I was with my boyfriend the whole time i wasn't still seeing him -my ex- I broke up with him for a good reason when I did.. And it didn't help how guys seem to hit on me alot it really gets annoying sometimes. and it hurt his trust me with but i did work very hard to earn it back and to this day he says he has no doubts and 100% trust me and doesnt care about my past but Me and my fiancé have been thru so much together it feels so good to feel happy with him but it's bittersweet because of how I feel and w knows ill be leaving soon but I'm proud to be serving the military and making a good career for myself and for us and I keep setting high goals for myself to continue to better myself in life for no only me but for God and for my future husband tho were not getting married right away were waiting Till 2014-2015ish not sure on a date keeps telling me everything will be okay I know and you don't have to explain yourself I forgive you as well but I wonder maybe it's just that I don't forgive myself and the more I keep talking about it It makes me look like I'm more guilty than I should be but mainly it just annoys him but he understands how I feel how I just feel terrible about the past he has felt the same too and still do sometimes. I just seem to have a strong conscious But I'm not perfect and I'm a lot more open with him and straight forward with him especially and others I just don't know what to do Idk if I'm just being overly emotional or just thinking too much but i don't want to push him away.. *please no rude comments And please don't judge me, I know this post may seem silly but it's really been concerning me and stressing me out way more than it should and I don't know who to talk too most of my friends are either busy with their problems or family's*

This post really confuses me. I don't understand your problem. There is a lot of copy and pasting at the end. But it seems that you love each other a lot by what you say. I can't give much more advice because the information you try to convey is very wishy-washy :S
