Should i be suspicious?

Does it sound like she’s looking out for our best interest or maybe just trying to get us to spend more money on a vendor she may know?

I’d guess the answer is yes to both. She is running a business and will make more money based on the amount you spend (likely). She also probably has worked with couples who have regretted not having a videographer. It doesn’t sound like she’s being that pushy by saying she’ll keep one in mind. If you feel that strongly about not having one, let her know that definitively.

I agree with above posters, she's likely just making sure you won't regret the decision or have discussed it.

Its something that isn't important to my FH and I either, just let her know -as long as she isn't being pushy about it

Sounds like best interest. I am currently planning mine and we were only going to with a photographer as well. A coworker suggested we do the videography because she regrets not doing it. Think of it like this, you do the videography and your mother starts getting Alzheimer's, wants to see it since she can't remember. now you have a way of sharing it with your mother, or even elderly family that are too ill to travel.

Seems like she's looking out for your best interest. Honestly, me and my husband weren't going to get a videographer but we got one in the end. We got a trailer and it was beautiful and then uncut footage of the day. We were happy because the day goes fast and it captures those moments of the day that you couldn't see or whatever.
