I just had a big fight yesterday with my boyfriend and I thought about this:
To give you some background:
We were at a party and due to my social anxiety I was really stressed and after a few hours I became really upset with him, because I felt like he ignored me. So I started a fight and said some things that hurt him.

The whole time I felt like I was in the right, because my emotions and fears felt so real. Now I'm at a point where I start to realize, that I was unfair.
Yes, we can expect our partners to listen to us and take our mental issues seriously, but they are not responsible to fix us in any way.
It's important to let them know, how you feel, but they are not your therapist and your anxiety never excuses your bad behaviour towards them. 
Maybe this seems obvious to a lot of people, but I think some people don't realize, that this "bad behaviour" can come out in many subtle ways, f.ex.:

- You should always assume that your partner has good intentions and doesn't want to hurt you. When we're anxious, we tend to worry more quickly, that our partner doesn't love us or doesn't really care about us. We also tend to interpret things they do in a very negative and irrational way. When you have feelings like that, don't attack him/her. Instead try to calm yourself down for a second and try to ask for your partners love/attention in a calm way.

- Your partner has his own stress and problems. Don't start a discussion late at night, when your partner has to get up to work early. Don't be hard on them, when they sometimes don't have the energy to listen to your worries. Of course you should talk to someone about you issues and sometimes your partner can be that person. But if you truly have severe anxiety, seek a professional therapist to talk to regularly.


I would love to hear other thoughts about this:
If you are the person with anxiety, what are some tips to control your emotions infront of your partner?
If you are the person, that is in a relationship with a partner with anxiety, what are the things, you wish they would stop doing?
