Is it harder to quit smoking because of boyfriend ?

Met at student house. When we didn't know each other that well but were on the friendly terms I went though a couple tuff days. One late evening he saw me outside in the garden ,I was very sad because there was a guy I had a crush on but there was no sense in investing in a relationship as he was the popular man whore, behaved awfully and didn't care about his bachelors at all.
So my (now) boyfriend offered me a smoke. ''Just for this one time''. (He's not a bad guy, quite responsible and with a head on his shoulders)
But as you know there was a second and a third and now I try to quit. It's a 3rd year of me smoking and us being together.

One day when I was on a 3rd or 4th day I had a ton of assignments to do and got very nervous as I usually do during the craving. He told me calm down and eat some snickers. After I asked him what he mean he explained that he meant a cigarette.
It made me a bit pissed inside as he didn't support me. I wasn't even mad at him,just simple-''crap, I forgot that , dammit , ramble ramble....''.
It was and is hard already and I want to talk to him about it when I next pick the day to start quiting this crap. But what do you guys think?
Is it my nicotine craving over reaction or his lack of caring about health whats or ever?
