Will me and my boyfriend last?

Me & my boyfriend have been together 8 months today, we’ve had are ups and downs and that, but we’ve always managed to sort them out, he never told his mum about his girlfriends, didnt want too, always wanted too keep them to himself, didnt find it important, but he’s told her about me, and she likes me, and he said he told her about me because he was serious about me, I’ve met her & I’ve stayed at his, he’s stayed at mine, he does every weekend, we haven’t got 1 day since we’ve been out where we aint spoke, I speak 2 him from the time I wake up till the time I go asleep non stop, I talk on the phone too him till 2-3 in the morning, and speak 2 him again when I wake up, we have jelousy problems tho, if we’re out I accuse him of looking at some girl, and he’ll accuse me, I haven’t been in a relationship like this before, I’ve always been hurt/used by other boys, and he’s been hurt/used by other girls, we buy eachother stuff, and everything, he’s spent over £500 coming too see me, and we’re even talking about kids, we’re not guna have one straight away but we’ve been talking about kids for the past 4 months, we’ve made a bet like £10000 that he’ll finish me between now and 60 years time, I said that nothing last’s forever, and he wants us too, he’s swore down on his mother’s life he wants us too work & everything, I’m so happy with him its unreal. The way this sounds, do you think we’ll last forever?
