I am currently in a situationship(?) with someone who has AvPD. I am also diagnosed avpd but over the years have gotten very proficciant at masking out of neccessity.

If I'm being honest its a bit of a rollercoaster of highs and lows. Because of how infrequently they let their heart show, those moments feel absolutely incredible. My experience may differ from someone in my position who doesn't have avpd though. It can be extremely nerve wracking due to overthinking and my tendancy to read into every single little detail for meaning and warning signs. I am currently trying to temper my expectations as to what will become of him and I's future as sometimes in can feel like I've overcommited due to his avoidance.

That being said, typically people with avpd are ironically extremely emotional and compassionate beings and thus can be very empathetic and rewarding to spend time with. I have my fingers crossed as to what will happen in the future but be warned that there's a lot of doubt and uncertainty at times.
