<human>: We met Feb 2010, and dated for about 3 weeks. I stayed at his place a few times, no sex. I didn't feel like I was getting the attention/affection I needed at the time, talked to him about it, and didn't hear from him again...

Until NYE 2010/2011. We got back in touch, went on a few dates again. For the last 12 months, our relationship basically goes like this: He'll get in touch with me, we'll hang out after work during the week (aka, no sleepovers, I work too early in the AM). After a few drinks, whenever I leave he'll insist that I should come over for dinner again the next night, and I'll promise to text him the next day. When I do, he doesn't respond, and I won't hear from him again for anywhere to 1-4 weeks. Repeat every month for 12 months.

Recently he's said he wants to get serious. I really like him, I like being around him, and we have a good time together. He is what I would call "the marrying type". He's someone I would be able to trust, responsible, stable, upstanding guy, great character, etc. I really want to try to have a serious relationship with him, but I'm afraid... what if I change my mind? How long do you "try things out"? I was engaged previously, and being dumped after 3 years is NOT a fun thing. I don't want to do that kind of damage to someone else...

Give me the gist of the text in a nutshell
<bot>: After 2 years he (30M) wants to get serious and I (24F) want to give it a shot, but when does it become leading him on?
