My heart and mind are split in two help please?

so on tuesday it willbe my 2 year annivesrsery with my boyfriend. in those two years we've of course had alot of problems. sometimes i feel like maybe we are way too opposite for one anotherhe is clingy and wants love allthe time andi don't he is planned and i just go with the flow. etc... but my main concern is his trust issues i haven't done much of anything to makehim not trust me. he says he has workedon it and he does give me more space but i can't tell if he is just shoving it tothe back and has not actually been dealing with it. sometimes if feel that our relationship is just physical hen he does something real sweet to confuse me. idon't know what i should do with our relationship. ifyou have advice let me know or e-mail me please. sorry about the typos themeyboard is too small for my fat fingers. and one last thing that really sets us apart is what levl of relationship we want i think he wants to marry me he has said so very early on and i have always told hi thats not what i wnt for my life i'm only 20 and he is 2. ugh please help.
