Please help me with my choice?

i was going out with a guy we didnt have the best relationship, yes we loved eachother had a good life and he could be very affectionate but he would be really immature at times doing things like ditching me for mates to go down the pub when we were spose to do something, i often felt let down and hurt by him it embarrased me aswell infront of my family as they always saw me upset over him. after i would be angry and tell him enough is enough he would then call text and come roand upset beggin me to forgive him saying how he was sorry and couldnt loose me and how much he loved me. this little routine went roand and roand for a whole year over and over again. hed let me down, id be hurt say i had enough, hed be really upset apoligise persistantly and id take him back. we then had a big split when he we went to watch a football match in town with his mates, i forgot my i.d stupidly and couldnt get in to the second place we went to it really anoyed him we ended up falling out and he stayed out with his mates leaving me to go home in tears, he then turned up at 4 in the morning drunk shouting at my window and banging at the door wanting to speak to me, he even broke one of the gl pains in the door bangin on it so much. i let him in reluctantly as he had hurt himself and i ended up having to call his dad to come and get him which was awful. i was in pieces my brother came to look after me next day and was really anoyed at my boyf obviously! i thought thats it theres noway i could ever take him back now! my boyf in a mess next day was extremly appauled at himself for how he had acted, said how sorry he was and how much he loved me again and couldnt believe he did what he did he beged me to realise how sorry he was. hes stoped seeing his mates who have such a bad influance on him now and he has also stoped drinking as he realised how badly it affected him even stoped going to the pub. we started seeing eachother again exclusively recently to things how things went and if i could forgive him. he told me how he had got his priorities in order now and wanted so badly to make everything up to me and treat me the way i should be treated. hes been great really affectionate, loving and alot more grown up. however its been 2 months now that we have been exclusively seeing eachother and i am no closer to knowing what i want to do, i set aside time to think lots of time! but i never come to a conclusion. id be scared of telling my family that we were giving it another go there great but would be very weary and would think im making the wrong desision i no why beacuse they love me and hated seeing me upset before. me and this guy get on really well when were together we always have but i dont know if i can forget the past and learn to trust him again. im getting really stressed out i love him still and he loves me very much very much but i just dont know what to do for the best, i need to make a final descision once and for all but every time i try i just cant i ask myself all sorts of questions but never get to an answer. i love him but am i in love anymore after everything i dont know? I sometimes look at him and focus on things like hes not that attractive and ive never cared bout that before. however the thought of not being with him or him being with anyone else upsets me too. i think im possibly just struggling to forget the upset he caused me i need to decide what to do, please help no matter how many times i go through things i cant decide with things like fanily events coming up i really have to decide now, please anyone please help me
