Very confused & don't know what to do

This is pretty long so please bare with me as i need help/advice,thank you..Iv been with my boyfriend for 15 years now,we are not engaged or married & don't have kids,we don't even live together...We don't go out or anywhere really.we'v never been on holiday..He had a week off recently & said this time we'd go away somewhere just for the day,of course i was excited & happy,he drove twenty odd minutes to a fishing shop,i told him to head in himself as i didn't want to be in his way when he'd be looking round,but he just turned the car round & left me home...He doesn't like the cinema & doesn't believe in valentines day..I used to try going out with friends but he'd be always txting me & if i didn't reply quick enough he'd ring me annoyed,asking why i won't reply & that..I went out with one friend once,i asked him to join us but he said no,he followed me into the pub,hid behind a pillar so he could see us but we couldn't see him,he then started txting me,accusing me of being with another man,asking me who i was with & was anyone chatting me up etc etc & he looking straight at us,it was the barman who told me,when he coped i knew,he literally power walked out,i followed asking what all that was about & he just started high pitched screeching at me...So i stopped heading out because this is what id get.I can't do much because he doesn't seem to like it if i do,it would start a fight..Yet he's allowed do whatever & go where ever but it seems like im not allowed,one rule for him & loads for me..He was out in the middle of a lake fishing with his mates,he rings me asking what i was up to & that,when i told him i had called into a friend,he went mad at me,demanding to know why & saying how come i wouldn't call to him,even tho he was off with his mates & i see him everyday...There's more but i'll stop on that one..Iv gone off having sex with him & now he bases the whole relationship on this..Iv lost count of all the times iv tried talking to him & telling him that we need to do other things & that not just have sex & that's it,but his reply to that is,oh now iv to do stuff with you in order to get laid..Iv explained to him that in a relationship it's not just sex,it's sharing a life together & doing stuff together,like going places,maybe going for a drink etc etc but he says that if i were to have sex then maybe things might get better,but sure that's not solving anything for me tho,he doesn't get this at all..Now please don't get me wrong,sex is a big part in any relationship,but it's not everything,he's made it EVERYTHING..I can't have a proper conversation with him,he brings sex into it,any chance he gets he's trying to feel me up..He'll start this thing where he'll ask,any chance of sex,i'll say no because iv lost interest,it does nothing for me anymore & i will yet again explain why,but he won't listen,just says oh iv to do stuff with you & that to get laid...He'l then tear out of my driveway,then txt 2-3minutes later asking for sex again & this will go on for a while after,he gets so annoyed with me & makes me feel like such a mean bad person but i can't help it now anymore because he's not willing to try sort out what my problem is,it's all him & how he feels & what he has to put up with...Im so confused & upset..Iv asked him does he want to split & stay freinds but his first words to that was,then you can come & go as you please & he'l be upset if he were to see me with anyone else or he thinks i'll head abroad etc...He's really pist at this sex situation,that's all he's focusing on & i get it alot off him for it & he's not happy with me but yet he doesn't want us to split or that,he doesn't know what to do & i don't either..What to do now is the question so i need advice/help big time..thank you

This is so complex but looking at your situation your bf is lacking confidence in this relationship but he bonds well with his mates etc. so he uses sex with you as an outlet. But you need to make him understand it takes to make a relationship

Iv lost count of the times iv tried talking & explaining ,he's just to focused now on sex,nothing else seems to matter to him..He's not really a people person (it's hard to explain) he has id say 2-3 friends but they don't hang out to much or that,he doesn't do anything bar go to work 5 days a week,go home,watch some tv,maybe have a nap,maybe go fishing or shooting & that's it with him..He'l come out to me,we might go for a spin around for 10-15 minute then im dropped home,even if i did have sex with him that would be it,do nothing else bar that,everyday..so i just lost interest in sex & now this is the whole relationship to him..
