<human>: Hey guys, so basically I met my GF at my workplace, we didn't date while we were working there but we were pretty close friends. we both stopped working there and later on by coincidence started hanging out together and eventually started dating. 

an issue that was a bit bothering to me from the start was her age, I always knew she was quite older than me and I'm pretty young so we're not in the same place in life so to speak. 

but she's not interested in marriage or children yet and I like being with her so overall I think it's okay. 

Anyway, at the beginning of the relationship she mentioned she was bummed because "it was her 30 year old birthday" and She's in her 30's now and it sucks because she's getting old etc,

I brushed it off, and anytime we had a conversation about our age difference she failed to mention her real age. 

skip forward to 8 months later, we were watching a music clip on youtube, and the year it was from was 1985. so I run a quick calculation in my head, and ask her "wait, you were born in 1985 right?", she nods her head in disagreement, so I ask "1986?, 1984".

she says nope, I'm actually 33 years old... 

and I was like wait what? and then she told me she was hiding it all this time because she was afraid I wouldn't want to be with her because of her age and she wanted to bring it up a few times but was too scared to do it. 

and then I told her I mind less about her age but more about her lying to me about it all this time, to which she replied that that's just what im telling myself, and that what really matters to me is her age. In her defense she later told me she's sorry for that and that she believes me what bothers me the most is that she failed to tell me. 

Anyway, I can understand why it was hard for her to bring it up, but it still bothers me. my question is : how big of an issue is this? thank you.

Can you give me a shortened version of the text?
<bot>: Gf told me she was 30 years old at the start of relationship, 8 months later she casually mentions she's actually 33 (almost 34) years old. how big of a deal is this?
