First time I have seen boyfriend in 5 months, don't know if I still love him?

My boyfriend was deployed to Afghanistan 5 months ago and has recently returned. When he left, I felt like my world was ending and that I couldn't live without him. Whilst he was away, I wrote to him every day and spoke to him whenever he could. We talked about the future, about moving in together when he got back, about getting married... Etc. I missed him so much every day sometimes I felt like I couldn't cope, especially seeing things on the news and hearing such terrible things, I had to hope and pray for his safety every day. I missed him so much it hurt.

Last week the day finally came and he returned home safely to me. I am so relieved that he is safe and sound and unscathed, but there is now a problem. I can't stand being with him anymore. It felt so lovely and relaxed having him back, but I had gotten so used to him being away and coping by myself that I am struggling having him back with me. He has been living out of my pocket for the last few days and I just can't bear to be around him anymore. I hate him sleeping in my bed because he keeps hugging me in the night and waking me up, I hate eating with him because he makes me eat unhealthily, I find it exhausting having to entertain him all the time and I am not really bothered bout sex either. Tonight I had to make up an excuse not to be with him to which he almost cried in response, but I needed time alone. Is this normal or have I fallen out of love with him? I realise it will take time to readjust but this is such a strange feeling I don't know whether it is normal and will pass or that we have really grown apart. Help!
