Smothering (depending on the motive) is not such a great gift to give in love and is not what you need, you might think you need it for moments at a time to feel what its like, and thats ok to try in moderation, whereas in your case (not in moderation) what then happens is that moments and the feelings brought on by those intense moments (namely make or break moments in this case) are for I can only suppose an adventure in love, and what I guess probably made you feel like getting engaged for emotional security(or other/whatever the thing).....like the basics of a place for love to establish but which can turn out in residual/sticky mess, but to develop experimentally in a brave (and/or sometimes nieve) step is sometimes necessary like many people young invariably do anyways~ to find out these things and what spontaneity can do. :Plug-in/Cue-hamster-rush-at-a-pace-smiley:
Ya know the nature of life in a kaotic world is haphazard, but at least you made a quite solid intention I guess about that (proposing engagement) which shouldn't be a half-hearted thing or measure, but until sanctified, professed/(whatever) its just as off as on right(?) until comes a time like the situation your in now and need space to think/chill/break/calm down, etc.
However cherishable those moments, and risk partaking, your learning sees now how perishable they can be too if overly smothered by either one or the other (or both, not so bad).
With just one doing the smothering (apparently him) you will sure enuff kick off, but its good you told him straight earlyish
and that he won't need to wonder for a month about what your immediate feelings are <<---Good thing (and to have not suppressed is good)..... However both you's are sure to be evaluating the risk you've undertaken in urge of spontaneity (and what you've learnt from it) by having entered a relationship as you did full on in a short space of time.... (but perhaps thats what felt right at the time).
