My boyfriend says he cares a lot about me, misses me when I'm not there loves being with me but is this love?

He has recently sais he doesn't know if he is in love with me? He says he does not undersatnd his own feelings and finds it really difficult. I ended the relationship but he came back saying he was willing to try make me feel more secure by his actions and he thinks what we have warrants more effort.

Can he really not recognise love and wy is he so frigtened to say it? I am really confused as what to do? If he reallyhas problems wth his feelings then I am willing to give it another go? He says I am being unfair putting a time sacle on love.What do you think?
