just my take on this -

in some relationships - he sees gifts as OK - a sign of love - like with his kids. no danger or ambiguity there at all. no strings attached.

in some relationships - like with the perp(s) - he sees gifts a a means of control or manipulation - recalling feelings of victimization, vulnerability, and possibly guilt and shame.

for you - he may be confused as to which it is. he may think of it as friendship/love in his conscious, rational mind - BUT subconsciously feel the conditioned responses from the earlier abuse.

at least that's my guess.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
