Ideally you should not travel for some time, say for another 6 months, and then only leave for a few weeks or a month. In general you should spend more time inside the US than outside. If you travel in June for 3-6 months again, that could get you in a trouble. The rules you should care about is continuous residence (no trips over 6 months), physical presence (more days in the US than outside). Every time you spend over 12+ months outside the US or have too many trips / long trips, your residency maybe questioned by CBP.
