I dont think it's all that bad. It must be nice to hear your boyfriend tell you he loves you. Do you love him? Or like the idea of having what you call a "successful relationship" He does sound a bit dependent on you and obviously this is annoying you. Tell him! "Hey honey, your pouring on a little thick dont you think"? Then laugh He'll think your joking and he'll get the point.

"you only have one chance to make a first impression"
