What does してばかりいる mean?


I cannot get 干渉してばかりいる in the sentence below:

私の父はいつも私の私的な生活に **干渉してばかりいる** 。




ばかり after a verb ending in -tte or after a noun means "only" or "always", and
usually (but not always) has the a negative nuance: in other words, "only
interfering (and not letting me just do it without interference)).

In colloquial speech, it's sometimes pronounced/written ばっかり or ばかし.

An example with a noun:

ケーキばかり食べている。 (You only eat cake [nuance: you should eat something else])
