بعد الغيبة، صاحبتي سالتني عن الاخبار.

No. غيبة can also mean backbiting/gossiping about someone behind their back in other contexts. That is a very common meaning too.
Here, though, the context makes absence the right meaning:

• بعد الغيبة = after being away
• not after gossip

So this is a good example of how context decides the meaning.

Because in everyday Egyptian Arabic, subject + verb order is very common:

• صاحبتي سالتني = my friend asked me

This is more conversational than the more formal/literary verb + subject order often associated with MSA. So the sentence sounds naturally spoken.

صاحبتي means my female friend. In context, it refers to a woman.

But depending on context, صاحبتي can sometimes also mean my girlfriend. Egyptian Arabic often uses صاحب / صاحبة in ways that can mean either friend or boyfriend/girlfriend, so context is important.

Because it is built from صاحبة plus the possessive ending -ي meaning my.

When a word ends in ة, that ending becomes -ت- before a suffix:

• صاحبة = a female friend
• صاحبتي = my female friend

So the t sound appears because the ة is no longer in pause form.

-ني means me.

So:

• سالت = she asked
• سالتني = she asked me

This object pronoun attaches directly to the verb, which is very common in Arabic.

In more standard spelling, this would usually be written سألتني. In informal Egyptian writing, people very often leave the hamza out, especially in texting or casual written Arabic.

So:

• سألتني = more standard spelling
• سالتني = very common informal spelling

The pronunciation still normally includes a glottal stop, something like sa'altni.

Because سأل عن means to ask about something.

So:

• سألتني = she asked me
• سألتني عن الأخبار = she asked me about the news / what had been going on

Without عن, the meaning would be different. It could sound more like she asked me a question rather than she asked about something.

Literally, الأخبار means the news. But in everyday conversation, it often means something broader like:

• what’s new
• how things have been
• updates
• what’s been going on

So here it probably does not mean TV news. It more likely means she was asking for updates after not seeing the speaker for a while.

It is usually pronounced something like il-akhbār or el-akhbār.

A few useful points:

• the article ال is often pronounced il or el in Egyptian
• the ل is pronounced clearly here, because أ is not a sun letter
• the stress is on the last part: akh-BĀR

So the whole phrase عن الأخبار sounds roughly like ʿan il-akhbār.

A natural rough pronunciation would be:

baʿd il-ghēba, sāḥebti sa'altni ʿan il-akhbār

Or in a simpler learner-style transliteration:

ba3d el-gheiba, sa7ebti sa'altni 3an el-akhbar

A few pronunciation notes:

• ع is represented here by 3
• ح is represented here by 7
• gh in الغيبة is the sound of غ
• sa'altni includes a small break for the hamza

It is mainly Egyptian colloquial Arabic in tone and style.

Clues include:

• the casual phrase بعد الغيبة
• the everyday word صاحبتي
• the informal spelling سالتني
• the natural spoken word order subject + verb
• the lack of case endings

A more formal MSA-style version might be:

بعد الغياب، سألتني صديقتي عن الأخبار

That sounds more formal and less conversational than the original.
