Single and married?

So I've been talking to this woman she's married, I've known her since highschool, that was around 4-5 years ago that was the last time we met in person and recently I've been out of touch for years as well due to personal circumstances. However recently I decided that I'd like to talk to her again. she's married now but she also wanted to get back in touch once I reached out and we both reciprocated good appreciative feelings towards one another. Anyways, I wasn't planning on meeting up to hang out just wanted to hopefully talk on the phone occasionally or text as pals. She brought up hanging out in person and possibly bringing her husband to which I asked if that's what she wanted to do then perhaps we should meet alone the first time at least, I didn't exactly feel as if I wanted to hangout with a woman and her husband as it'd be fairly awkward. Anyways do you think I was wrong to suggest hanging out alone with a married woman as a single man? I have no intentions of trying to romanticize it at all whatsoever, I used to have feelings for her and fear it may complicate things in the future. What would be the best plan of action?
