The following interpretation only applies IF these aspects in synastry have an orb of no more than about 5°. If it is wider than that, don't include it as an aspect.You can expect obstacles to a sense of fulfillment in a relationship with him. This will not necessarily show up or be felt early on in the relationship, since Nodal contacts are more surreptitious, tending to show later, well after initial attraction, and the emotions of a new relationship.
The mutual hard Saturn-Nodes synastry aspects show there is likely some conflict between your notions of purpose, future, and fulfillment. You may or may not be able to resolve this, depending on how much genuine affection and willingness there is between you.
If there are other factors strong enough to draw you together, your attention in uniting the relationship will need to be focused on concrete small steps forward, rather than bringing in inflexible ideas of your future together. Very likely one or both of you will give up some ambition or some material attachment to find middle ground for the relationship's unity. One or both persons may not be willing to do that.
The difficulties in this kind of relational aspect come most likely for the guy (with your Saturn square his Nodes) who may feel that too much responsibility or expectations fall upon him. You may feel something similar. So it is important to (a) be clear about your life direction and purpose, (b) be clear about your own responsibilities in that rather than begin laying any of it on him, (c) expect obstacles and face them together in unity rather than resorting to blaming when frustrations come up.
These aspects do not prevent a relationship from being close or intimate. Some of us may even have synastry like this with family members. However, typically with someone we want to be an intimate partner, we need enough supportive Mercury, Venus, Sun, Moon aspects with some Jupiter to give the affection and energy to overcome those challenges.
